A Hong Kong writer, Tao Jie, once said: When you are old and look back on your life, you will realize that: when you went abroad to study, when you decided to make your first career, when you chose a person to fall in love with, and when you got married, are all in fact drastic changes in your destiny. It was just that at that time, standing at a fork in the road and seeing a thousand booms in the wind and clouds, the day you made your choice was, on your diary, rather dull and mundane, and at that time it was thought to be an ordinary day in your life. The pain you felt, other than being sick, was brought on by your values. And not real. There is no need to stand at the age of 50 and regret the life you had at 30, or the love you had at 17. We can't stand on the heights of later years and criticize ourselves back then, it's not fair. If we were to do it all over again, we would still make the same choices with the same mind and experience. So learn to make peace with yourself, and accept yourself for who you are at each time.
