Life is difficult. It is a great truth because once we truly understand and accept it, then life is no longer difficult.
Most do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. What makes life difficult is that the process of facing and solving problems is a painful one. Problems cause in us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.
But we are wise. It is in this whole process of solving problem that life has its meaning. Problems are the serious test that tells us success from failure. When we desire to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school teachers set problems for students to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, those things that hurt, instruct. It is for this reason that wise people learn not to fear but to welcome the pain of problems.
I hope all of my students are the wise people or they all can become wiser and wiser after they face all difficulties in their life.
