Brother as someone who is the Probably the Most Confident person on this side of the sun... You must sit back and do you before you worry about anyone else.. Find yourself and take ME time. Im confident because I believe in myself and dont care for doubters until after I proved them wrong.
No speaker or anyone else can help you gain confidence. You do have those that fake confidence to hide there weak shell. You must break out of wutever it is that is holding you back from yourself.
Confidence is inside YOU. You cant buy it or deny it. Everyone has it, Just some dont/wont believe enough in themselves to show it.
One thing about breaking up, You can let it break you or you can let it make you stronger. I love to be alone, because it gives me time to be me. Everyone wants someone but dont find yourself needing them to the point you lose yourself.
