When things seem difficult, work even harder.

If you have heart, you can achieve anything. Remember, life is what you make of it.

1. Prove you can accomplish something by working hard at it - don’t give up.
   Whenever you feel like you can’t achieve something because you’re too weak, too stupid, too tired, etc., keep working hard at it instead of giving up.

2. Always look forward.
   Sometimes, no matter how hard you try, no matter how good you are, you might fail. When this happens, don’t complain and don’t blame it on your misfortune. Instead, look to the future and continue working hard. Use your failures to learn better ways of handling situations, and persevere on!
