A few years ago I discovered Trello, and how I organise things hasn't been the same since. If you're not familiar, Trello is a digital tool that essentially allows you to create lists of items, where each item is an individual card. This week I came across another service that caught my attention with a similar look: Sunsama. It's a calendar app built to look and feel like Trello, and I'm pretty stoked on it.

Your to-do management system says a lot, maybe everything, about you. We've organised the major systems according to their Dungeons and Dragons alignments, making value judgments with which no sane person could ever disagree.

As we have argued in the past, email is not the problem - we are. And it's not just the productivity drain or the antisocial effects of constantly checking our phones and computers for new messages.

There are psychological ramifications too. By constantly looking for new information and tasks from other people, we are degrading the importance of the things we want and need to do. This flowchart explains what you're doing wrong - and how to fix it.

Email can be a distracting time sink for any office worker. But sometimes, it's best to get it out of the way. Over at Harvard Business Review, contributor Dorie Clark makes the case for checking email first thing in the morning.

Do you always install your air conditioner on a sweltering summer day, or rush to do your taxes days before the deadline? For absolutely necessary tasks like these, a to-do list isn't always enough. You need to block out time on your calendar, and treat these tasks like actual appointments. We've listed all the best to-do items to turn into calendar items.

There are some excellent time-tracking apps out there, but if you prefer the comfort of good old Microsoft Excel, here's some good news. A Redditor made an Excel-based to-do list with built-in time tracking, and the template is free to download.

When it's time to buckle down and get some serious work done, we trust that you have a go-to productivity method or technique that functions best for your workflow. At Lifehacker, we talk a lot about the different techniques you can use to spend more time doing, and less time organising or thinking about doing. If your current method is working for you, here are five productivity techniques that have proven highly effective for countless people.

Your Mac comes packed with a perfectly fine calendar app, but it's lacking advanced features, multiple ways to view your calendar and external service integration. For all that and more, we like Fantastical.

As more of us are working remotely these days, more digital task managers are offering collaborative features like sharing specific tasks, commenting on tasks and making shared to-do lists within your team.

Regardless which productivity system or method you prefer, Zenkit is an all-in-one webapp that can help you manage your big projects and activities using the system that works for you. It's free (for now, it's in beta), but it looks good -- minimal and distraction-free, but powerful under the hood.

Chrome/iOS: Handle is the productivity add-on that Google should have made. It seamlessly combines emails, to-do lists and calendars to make Gmail your central productivity hub.

When you get emails that require action, you want to make sure to add it to your task list as soon as you can, and the best way to do this is to connect that list to your email. This way, you can add to your to-do list without leaving your inbox.

Android/iPhone: TickTick is a powerful syncing to-do manager that's seen a lot of improvement since its launch. Today, it's getting a handful of new features.

There's a solid case to be made for going public with your goals. You can use the same method with your to-do list, and beyond the accountability factor, writing your list for someone else can help you make it more succinct and efficient.

Android: It's been a while since we checked in on Tasks, an open source clone of the gone-but-not-forgotten Astrid to-do app. Tasks has come a long way, too, and is even more powerful than ever -- and still free for everyone to download and use.

I've been using pen and paper for most of my organisation and to-do lists for the past six months. I've experimented with different analogue systems during that time, and tried things I made up myself to figure out what suits me best.

As I experiment, I always keep an eye out for any new ideas or systems that might work better for my workflow. I came across an analogue system recently that's almost too simple, yet quite clever in some ways.

Mac: Trello is one of our favourite organisation tools, but one potential downside is the lack of a native desktop client. Paws jams Trello in a desktop app for Mac, complete with notifications and a handful of keyboard shortcuts.

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.

To-do lists keep track of tasks we have to do, but they hardly ever provide actual motivation. A small tweak to your productivity method can solve that problem pretty quickly. All you need to do is start maintaining a "break list" instead, and you'll find yourself more eager to get things done.
