Always try and find something that makes you happy when times are tough. It can be the simplest of things. For example, when I was dealing with some heavy depression and became suicidal, one thing that helped me get through that dark period was a concert that I had tickets for in two weeks. But it doesn’t have to be that big. It can be as simple as when I finish this paper, I get to go play basketball. When I get off work, I get to see my friends. The point is when life is hard and exhausting, look for a bright spot and focus on that.
