Ditto on above answers. Also be careful on one-time only entry as you can DQ yourself with additional entries.
How you look at a situation is very important, for how you think about a problem may defeat you before you ever do anything about it. When you get discouraged or depressed, try changing your attitude from negative to positive and see how life can change for you. Remember, your attitude toward a situation can help you to change it -- you create the very atmosphere for defeat or victory.”
