Self esteem is an option you have to build for yourself.
First of all, make a board with two sides.
Your goods and your bads. Your true goods, the exact things that makes you smile for yourself.
On the other side, your bads have to be your future goods.
The things you have to work hard in order to correct them, to change them.
Bads are really good when you use them to see how far you can go.
Find your two sides. It’s really useful to know how bad you can be and how good you can really want to be.
Something in the middle will help you to recognise yourself and continue your try to reach your best.
