The greatest power God gave us is the power to choose. We have the opportunity to choose whether we're going to act or procrastinate, believe or doubt, pray or curse, help or heal. We also choose whether we're going to be happy or whether we're going to be sad.
No matter how bad someone has it, there are others who have it worse. Remembering that makes life a lot easier and allows you to take pleasure in the blessings you have been given.
