Most of your working hours are probably taken up by someone else. Your boss or your clients want you to do their stuff. If you're not happy with your situation, give yourself one hour a day where the only boss you have is you. Photo by Shane Adams.
Personal finance site My Money Blog relays this handy advice from notable investor Warren Buffet. We're often tempted to work extra hours in order to improve our lives. A little extra money never hurt, right? However, you may be better off stopping work at quitting time and spending that extra time working on yourself. Learn a skill, work on your side job, fill out your resume. Something that benefits your goals, not someone else's:
If you're an administrative assistant making $10 an hour and you don't want to be, don't just sign up to work another hour for $10. Working longer is not necessarily the best idea. Instead, give up the $10 (or $8 after taxes), and improve yourself in some way or create something so you'll be making a lot more. There is no one solution, look into yourself. Nursing school? Investment books? Finding a mentor?
Note that this shouldn't be confused with leisure time. Your regular boss wouldn't like it if you spent your time on the clock slacking off. So don't spend your hour watching Netflix because it's good for you. Get a plan to improve your life, then implement it little by little each day.
