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.
