Confidence is a weird thing, a lot of people believe you either have it or you don’t, however that’s not necessarily true.
Confidence comes from repeatedly doing a certain task over and over until you believe you are the best at it, only then will you feel supreme confidence.
Let’s take Connor McGregor for example, in his prime he was able to walk around saying what he wanted, doing what he wanted and he could because he would destroy any competition, however he lost to khabib and went on a downwards route after.
Another example would be Ronaldo he has always believed he is the best, trained like the best and this is why he’s had such a successful career…
In conclusion confidence comes from self belief and continuous effort and improvement at whichever subject or activity you would like to become better in!
