Start calculating your ROI: Return On Investment.
Paralysis-by-over-analysis stopped real quick for me, at work at least, when I realized that most people won`t go the the length of analysis that I did. Searching for the lowest common denominator, cover-your-ass, or politically correct answer always seemed to come out of the (promoted) office politicians. After a couple of deceptions, one adapts.
I am an introvert and this sort of over-analysis takes over when I have no clear goals.
Run your life like you would run a small business. Focus on what gets rewarded (results). Yes, there will still be self-talk. But having clear goals cuts it by many times, and the internal chatter is solution-obsessed, so it doesn`t go into endless loops.
I learned that 2 seconds ago.(Will Smith in Wild Wild West remake). Now that`s ROI.
