It's become a lot easier for me to hang in there from having accepted things in the past and not being angry about them anymore. Even with new things that come up or unwanted reminders of the past, I'm still able to accept all of it lately. This makes it so much easier to focus on staying positive and on tasks that I wish to complete. I don't feel so burdened by it anymore, even if I'm just another short guy.
In other words, I'm capable of studying anything I'm interested in without ever feeling disheartened about not getting it. It's a nice turn of events for me now, and it's just so awesome how powerful having a positive attitude really is.
