There are only two days in the year that nothing can be done. One is called Yesterday and the other is called Tomorrow. Today is the right day to Love, Believe, Do and mostly Live.
It is important to have determination and optimism and patience. If you lack patience, even when you face some small obstacle, you lose courage. There is a Tibetan saying, "Even if you have failed at something nine times, you have still given it effort nine times." I think that's important. Use your brain to analyze the situation. Do not rush through it, but think. Once you decide what to do about that obstacle, then there's a possibility that you will achieve your goal.
Drop the idea of becoming someone, because you are already a masterpiece. You cannot be improved. You have only to come to it, to know it, to realize it.
