Two things:

1. For anything to succeed you need to have all the factors to be right and for anything to fail you just need one factor to be wrong (aka there are more chances of failure than success).

2. Analyse the failures, don't just get over it. Ask questions about the failure to learn about it so that the learning can help you in future.

Get over the idea of optimism and pessimism, these categories will never ever help you in any situation apart from social talks where people just feel proud/whatever of classifying them in these categories.

Very good insight. getting feedback from failures do make one improve.

I shall carry your advice at heart.
