There is a lot of truth in what you say about fear and how to confront it.
It is true that we all have fear and it is not always bad because it allows us to be alert.
But, for me it has been bad to be afraid of failure because in some important stages of my life I let fear win over hope and I missed out on things I wanted and I didn't even know if I could achieve them because I didn't try.
And, that happened to me with a woman I didn't fall in love with because I feared she would reject me or with trying a new job because I thought I couldn't or leaving for another country for fear of not meeting expectations.
In the end, it is better to fail in the pursuit of happiness than to stop being happy for fear of failure.
Happy weekend.
Cheers and greetings.
