I have been confronted with many difficulties throughout the course of my life, and my country is going through a critical period. But I laugh often, and my laughter is contagious. When people ask me how I find the strength to laugh now, I reply that I am a professional laugher.
The purpose of our life needs to be positive. We weren't born with the purpose of causing trouble, harming others. For our life to be of value, I think we must develop basic good human qualities - warmth, kindness, compassion. Then our life becomes meaningful and more peaceful - happier.
No matter what activity or practice we are pursuing, there isn't anything that isn't made easier through constant familiarity and training (I think you can apply this to soccer as well)
We must work to resolve conflicts in a spirit of reconciliation and always keep in mind the interests of others. We cannot destroy our neighours! We cannot ignore their interests!
I believe all suffering is caused by ignorance. People inflict pain on others in the selfish pursuit of their happiness or satisfaction. Yet true happiness comes from a sense of inner peace and contentment, which in turn must be achieved through the cultivation of altruism, of love and compassion and elimination of ignorance, selfishness and greed.
It may seem unrealistic to think we can ever become free from hatred, but Buddhists have systematic methods for gradually developing a tolerance powerful enough to give such freedom.
