Don’t ever let anyone make you feel less of yourself, instead turn it around on its head and seek for how you can improve. Don’t close the loop in your mind about how you can improve. Ask yourself what you can be doing more consistently or differently to change the state of things. 

There is a need for time and patience on your journey, and not everyone can see or understand that. They can't see that you have had to deal with a different set of circumstances from them that has made you where you are, yet you will rise. The failures, disappointments? You still rise even higher!
