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.
Forgiveness doesn't mean forget what happened. If something is serious and it is necessary to take counter-measures, you have to take counter-measures.
I think every human being, born from mother, and at least the next few years, you see, received immense affection from our mother. So the child's first experience in this lifetime at the beginning, I think that immense affection from other is in our blood. So therefore, the whole rest of life, other people show you smile, genuine sort of closeness feeling. You feel happy. Even animals also like that.
Material objects give rise to physical happiness, while spiritual development gives rise to mental happiness. Since we experience both physical and mental happiness, we need both material and spiritual development. This is why, for our own good and that of society we need to balance material progress with inner development.
