When you meet something, like it and enjoy it; Avoid if you don't like it; If you can't avoid it, change it. If you can't change it, accept it. If you can't accept it, deal with it; If it's hard to handle, put it down. In fact, the hardest thing for people is to let go. Narrow alleys, memories of old dogs, mottled walls, can't be peeled off. Endless, it is the unfinished fate of previous lives in exchange for another date in this life.
