How can I become a stronger individual?

Hello, I am a 20 year old male and I would like to know how I can become a better person. I would like to know what I should do in order to become a human with a better atmosphere in almost every positive aspect imaginable. I would like to know of any ways I can improve my life so that I befriend a lot more people, have a strong backbone and most importantly be there for people and myself. Please, if you could give me a highly descriptive response I would appreciate it.
