My 16th productivity tip is to never get started if you aren’t 100% sure you will be doing that thing for several years.
You can never begin something and expect that you can stop.
Be so focused on where you will be personally or where your business could be in five years that you become paralyzed with the anxiety of ever starting anything.
After all, what good is it to just do something once and never be sure you can do it again?
Like I said about risk-taking, better it is to just never get started and wallow in a cesspool of self-loathing and misery than start something you may not be able to complete or even do for a long period of time.
There is also a side effect of looking to the future. You can be sure that your life will pass you by. Why focus on being content with what you do have when you can be constantly miserable about what you don’t have but want badly.
