Many times we are surrounded by people who transmit fear ... and it is not that they are ill-intentioned, but that it is their nature, they see everything bad or difficult, I have run into people like that and sometimes they have transmitted these fears to me , and I got to lose opportunities for that.

What you mention is very true:

“Its better to make mistakes with your own head, that to make them because of someone else’s opinion”

because only then will you know if it turns out or if it really is not worth it ... if you let yourself be carried away by others, you will always have the doubt ... would it have turned out well?
