I am who I am 

Only I can do me like I can do me

You can't teach self confidence

It comes with taking what others say about you

And making it irrelevant

The bully lacking self esteem needs to hurt others to feel good about himself

His words are worthless and mean nothing

The one who fails to care about what people think of him or her will be the one who reaches success

Happiness doesn't come to those who lose sleep over the opinions of others

Self confidence and high esteem of yourself will bring joy to your life

This is what I have

When you reject the need for approval from others, all that you do is successful

I can't say that success will bring you happiness, but positivity and the mindset you have will
