Even when a person has all of life's comforts - good food, good shelter, a companion - he or she can still become unhappy when encountering a tragic situation.

The very purpose of our life is to seek happiness.

If you serve others as fully as you can, what you do will be a source of inner joy.

If we choose an external marker as the measure of our inner worth, whether it is the amount of money we make, or others' opinion of us, or the success of some project we're involved in, sooner or later we're bound to be battered by life's inevitable changes. After all, money comes and goes, and thus is an unstable source of self-esteem, an unreliable foundation upon which to build our identity.

In Buddhism, both learning and practice are extremely important, and they must go hand in hand. Without knowledge, just to rely on faith, faith, and more faith is good but not sufficient. So the intellectual part must definitely be present. At the same time, strictly intellectual development without faith and practice, is also of no use. It is necessary to combine knowledge born from study with sincere practice in our daily lives. These two must go together.

Our every action has a universal dimension, a potential impact on others' happiness.

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)
