So far you have braved life. You have had obstacles and you have overcome many of them. You haven’t given up. Whenever you got knocked down, you got up.
Firstly, give yourself credit for that. You have clearly earned a Ph.D. in life.
And then realize that there are others who are also getting knocked down by life. And they need your help in standing up.
You, my friend, have seen it all. You need to step up and share your wisdom. You need to do your art.
