@javybar, I was also felt fear before coz I wrongly taken decision in my life. Many one happened under the my working job. But We can get lot of experience and scenery across fear & then mistakes.

Because of fear, we also tend to regret about actions we took or didn't take a long the way.

Yep..firstly we feel fear and then feel regret. Both things non-wanted things to our life. But everyone 100% not perfect. So can be mistake anyone. We are not a god. All are humans. As my suggestion is, let to do everything our life. Then we can find lesson and better solution.
