Change is easy and it does not take time if u know much about your 20 years if u don't know means u did not learn about the mistakes u have been doing . L
Just think if someone talks to you straight its better way learn and teach others....just let me know if u like That then What a person like me starts posting on timeline what will be the result?.
I am nobody and I don't have any rights to say u all this but I have no choice because they r ain't bad either.
Rest u know better........
Good luck.
