Since to me TRP is more about reshaping my overall life and this includes my mindset when I approach work, I thought I should ask here too.

I'm trying to jump to another career because my previous one was a dead end and, long story short, I'm trying to come to terms with the probability that regardless of how hard I'll work or how crazy I'll network I might eventually fail. Basically, to become risk-taker and be able to perform 100% with negative (yet possible) thoughts in my head.

A person from getmotivated said that one should be proud of his efforts, regardless of the outcome, because I can fail for something I had no way to know beforehand and therefore couldn't control. Therefore I should just "do what I want to do" without contemplating that it may all be in vain.

How the fuck do I do that? Working hard to learn constantly and at the same time pondering that there's a chance this might get me nowhere and be a complete waste of time is something I cannot imagine myself doing.
