Have you had anything that you wanted to do but did not? Then you should just do it:
(1) Set smaller and less ambitious goals – learn for fun.
(2) Stop gathering more than necessary information and stop analyzing the pros and cons, just do it.
(3) Sometimes an indirect pursuit will lead you to your eventual goal.
Action is always favoured against inaction. There is a saying in warfare that if you don’t want to be captured by your enemy, you should keep moving and not stay stationary in one place. But you might argue that a long time back some wise sage had advised you before that at times, inaction is also an action by itself. The difference however is that inaction stems from a period of action, and not from a period of no action.
