I wept because I had no shoes, until I saw a man who had no feet.
~ Ancient Persian saying
No matter how bad your life is, there are others who have it worse than you do. So, before you complain about something, especially something so trivial, just remember how worse it could be for you. Contentment in life is the only way to have real peace in your life. Learn to be happy with what you have and not with what you don’t have.
