You're alive and well.
Many people are no longer around, and many others are in such poor health they can barely function.
Yet every day, people with severe handicaps accomplish great things. If you are healthy and able-bodied, then you really have no excuse not to be the very best you can be. Opportunities come disguised as problems. Problems are a blessing, because when you solve them you grow as a person and you gain valuable experience. You learn things that can allow you to help other people solve the same problem.
