I found something worth pondering in the interwebz, here goes:
Internalise the idea that thinking too much leads to inaction. If you think too much, your mind will focus mainly on the negative part of it. The more you think, then the more opportunity you give those negative voices in your head to convince you not to act. Don’t wait until you’re ready. We’ll never be ready. You either start, or you continue thinking about starting. Realise that thoughts actually have NO REDEEMABLE VALUE. A million thoughts are worthless in comparison to 1 tiny action. Don’t linger on how much you have to do. Don’t linger on how effective your action needs to be. Simply do a tiny action as that is still INFINITELY greater than no action. So just start.
