NO. I believe you will LEARN much faster and gain the aptitude to fly the plane twice or even more faster than someone without the confidence.
Esteem and confidence can be IMPROVED dramatically by removing negative self talk and doubt. So no you can't tell them to just gain it, but it can be gained and there is a huge difference in one who is confidence vs one who is not.
You have every reason to believe in yourself. That's what self esteem is. You have every reason to treat yourself well and ensure that others especially do. You have every reason to not be manipulated behind sex.
Competence in a field is competence. Confidence is basically self esteem. We can tell someone that their self-esteem is too low, that they are cheating themselves. That they keep focusing on the negatives. That they treat themselves poorly. That they let females drag them down...
Self-esteem. All I'm saying is confidence or self esteem makes a HUGE difference, and like anything else it can be IMPROVED.
