Stop overthinking and just do it!
I’ll confess that at times I enter periods of chronic overthinking and analysis paralysis. This is something I’ve had to tackle and am still tackling. I probably can’t count the number of ideas I’ve had which I overthought till I did nothing.
The solution is to come up with a quick idea and general outline of whatever you want to do and implement it. Then see what works and does not work, gain some knowledge, and iterate from there. This does not only help in entrepreneurship but in virtually all areas of life.
This is a key trait which separates those who talk from those who act while those who talk watch.
