26 Time Management Hacks I Wish I'd Known at 20 - Etienne Garbugli

1. There's always time. Time priorities.
2. Days always fill up.
3. Work more when you're in the zone. Relax when you're not.
4. Respect your time and make it respected.
5. Stop multi-tasking. It merely kills focus.
6. Set up a work routine and stick to it. Your body will adapt.
7. We're always more focused and productive with limited time.
8. Work is the best way to get working. Start with short tasks to get the ball rolling.
9. Work iteratively. Expectations to do things perfectly are stifling.
10. More work hours doesn't mean more productivity. Use constraints as opportunities.
11. Separate brainless and strategic tasks to become more productive.
12. Organize meetings early during the day. Time leading up to an event is often wasted.
13. Group meetings and communication (email or phone) to create blocks of uninterrupted work.
14. Keep the same context throughout the day. Switching between projects/clients is unproductive.
15. Work around procrastination. Procrastinate between intense sprints of work.
16. Break the unreasonable down into little reasonable chunks. A big goal is only achieved when every little thing that you do everyday, gets you closer to that goal.
17. No 2 tasks ever hold the same importance. Always prioritize . Be really careful with to-do lists.
18. Always know the one thing you really need to get done during the day.
19. Break tasks into hour increments. Long tasks are hard to get into; feels like it all needs to get done.
20. Delegate and learn to make use of other people.
21. Turn the page on yesterday. Only ever think about today and tomorrow.
22. Set deadlines for everything. Don't let tasks go indefinitely.
23. Set end dates for intense or stressful activities. Everything ends at some point.
24. Always take notes.
25. Write down anything that distracts you - Google searches, random thoughts, new ideas, whatever. The point is, if you write them down, they'll stop bubbling up when you're in the zone.
26. Take breaks. Sometimes.
