Hello all,
I get enthusiastic about ideas daily but eventually I dont execute it as I feel it will end up in failure. The fear maybe due to my past experiences as I tried 2-3 side projects/MVP that didn't picked up much traction. I eventually shut them down. Now I feel I dont have courage to do it again.
How do you move past this mind-block and try once again?
So, your life intuition is telling you to not do it again: and it is right.
Learn first how to win customers. Prior to that you are not qualified to build a business successfully.
You can ask specific questions on that topic here, because a lot of know how in that area is on HN. But be specific, otherwise nobody can help you.
So, short answer to your question: Don't. Don't cope with a signal from your psyche, but interpret it right.
