It's Tuesday around 11am and you've just about had it. There's a pile of paperwork on your desk, 10 emails you need to respond to and a Slack message or two from your boss wondering when she can expect an updated draft of your project proposal. Never mind that you need to remember to stop at the supermarket on your way home and finally sign up for that password management system that's been a perpetual bullet point on your to-do list.

The last time you had a major project to tackle, you set a deadline for yourself -- and then came very close to blowing right through it. The result: You hastily finished (or pulled an all-nighter), and then swore you'd never repeat that experience.

Your to-do list is crammed full and you only have so many hours in the day. How can you ever get it all done? For starters, stop trying to figure out how to fit everything in. Instead, focus on the high-priority tasks that matter.

You've been working 70 hours a week, you're constantly on the go, and you still feel like you're behind in your work. The problem may not be that you're not working hard enough, but rather that you need to change your priorities.

The word procrastination has got a bad rep. But sometimes, you're better off putting off that task. It's all about identifying the right time to do something, says Rory Varden, author of Procrastinate on Purpose.

Everyone's wrestled with the "Where do you find the time?" problem. You only have so many hours in the day and you can't accomplish everything. The real problem, however, may just be your priorities.

Have you ever noticed how easy it is to make a to do list, but how much harder it is to actually finish it? Prioritisation makes a huge difference when it comes to actually completing that task list. The trick is to be as ruthless as you can stand.

They say necessity is the mother of invention, but if that's the case, laziness must be its father. After all, the beauty of laziness is that you'd rather do something you want to do -- even if that's nothing -- than work. Let's harness that desire and use it to be productive -- -so you have more time to kick back, of course.

The world is filled with things to do, make and accomplish, but not with a lot of time. This quotation from David Allen, the creator of the Getting Things Done productivity system, is a reminder that we have to remember what's important to do rather than trying to do it all.

"If you don't zero in a core set of priorities, nothing ever gets done because everything is too important." Former US national chief information officer Vivek Kundra made that point on his recent trip to Australia. It applies to national IT infrastructure decisions, but it also applies to something as simple as your to-do list.

Task Boxes is a method for organising task lists focused on creating a visual hierarchy of your to-dos.

Editor: Project manager and writer Scott Berkun knows how to get things done when you've got a team of people, a to-do list, and a deadline. Today he offers an excerpt from the updated edition of his best-selling book The Art of Project Management (our review), entitled Making Things Happen. Prioritisation is always more emotional than intellectual, despite what people say. Just like dieting to lose weight or budgeting to save money, eliminating things you want, but don't need, requires being disciplined, committed, and focused. Saying "exercise is important" is one thing, but ranking it against other important things is entirely different. Many people chicken out of this process. They hedge, delay and deny the tough choices, and the result is that they set up projects to fail. No tough choices means no progress. In the abstract, the word important means nothing.

Feel like you're spending far too much time on less-than-important meetings, phone calls, and other daily drudgery? Take a tip or two from the prioritising managers at General Electric. An editor at Harvard Business Review sat in on one of their training sessions and walked away with a few practical tips. One simple idea in particular can help overcome burdens you didn't even know you were shouldering.Compare your calendar with the priorities. Label the purpose of every regular or recurring activity on your quarterly calendar and highlight those activities that are connected with your top five priorities. This simple exercise will reveal where you're squandering your time.

Productivity blogger Scott H Young says that the key to getting more done is starting with the big stuff first and moving to the little stuff. He calls this approach "top-heavy": Being top-heavy means the bulk of the work is at the start. A top-heavy joke has a long buildup for a short punch line. A top-heavy schedule emphasizes the start, leaving more space at the end. He says you should tackle the most difficult, important, and largest jobs first and leave the rest for later. Sounds similar to the pickle jar approach: put in the big rocks first, then the pebbles, then the sand, then the water. Make Your Time Top-Heavy

The Web Worker Daily blog pulls a snippet from one of the latest business-advice tomes, Susan L. Reid's Discovering Your Inner Samurai, one that speaks to a way of choosing from all your possible actions (Answer email? Do research? Crank widgets?) when you don't have a logical next step. Reid's suggestion:Two priorities; one-month commitment. That's all. Of course, if you can, you might narrow that priority down to one. Most of us, though, unless we are in an extreme situation, will have two.That doesn't, of course, mean skipping everything else for one month, but dividing your year into 12 chances to hone in on something that could use a little more attention than it usually gets—like keeping a workspace clean, in my case. How do you go about giving tasks priority and choosing what gets done next? Share your own samurai code in the comments. Tip of the Week: Two Priorities/One Month
