The quality of your life depends on the reasons behind the decisions you take. If they are internal reasons, for yourself, you flourish. If reasons are external, you lose control and feel frustrated.
Your happiness will depend on the things you do when there's no one standing behind you, when there's no deadline, no sticks, and no short-term incentives.
If you just wait for the deadline to come near to start work, wait for your doctor to recommend you to exercise, wait for the next stick to prod you into learning something new, you will never catch up.
Instead of doing work for yourself and doing things that make you happy, you will be responding to the largest carrot and biggest stick. We all know how it feels. That's not the way we imagine our lives to be. It's a shame we live that way.
