When you commit, you are always exposed to risk.
Risk defined as the exposure to downside - to things unfavorable. When you commit, you are exposed to many risks.
There is risk to be judged, to fail, to be embarrassed, or to figure out a thing is not for you. All of which are painful to experience. Which is why many of us don't commit.
Yet, there is no upside without risk. There is nothing to be gained without committing to something.
So instead of never committing out of fear of going through pain, you need to commit and be exposed to risk. That's the only way to grow.
You can start small, but you need to, commit.
