Learning to believe in oneself is one of the way to make proud of themselves because if you don't believe in yourself, the people around you might not believe in you in return. There were a couple of scenarios that are like that about not believing in themselves and in return they doubted themselves and also to the people who look into them.
There were times or I think most of the times, before, that I don't believe in myself. I don't believe in myself that I can do it because I thought that that is my only limitations to myself but it turns out that I can do more than what I should think it is.
Whenever I doubted myself or not believing myself, there were people that notice because I will hesitate for a moment and that's the time that they can observe that I doubted on doing it. Just like what I did when I was still working in a corporate world where I sometimes doubted myself if I can do this and do that but I have tried in the best way and the best knowledge that I can and it turns out that I can really do it.
It's the motivation on believing oneself can do it more and you can be more confident on doing things the way it should. Well, there were a couple of scenarios that are like that. That is to be more confident on doing things and the more you are confident the more you can achieve for it.
As long as you have the right knowledge that you bring, you will not doubt yourself to stop believing it that you cannot do it. Well, there were mistakes that you can learn along the way and it is part of experience. I won't know if it works if ever that you always gain success, there were times that you gain failures and that's what a person improve more.
