Don’t hope for a life of no problems. That’s not going to happen. Life is problems. You’ll solve many, but you won’t solve them all and there will always be new ones.
Life is full of annoyances, because nature isn’t harmonious (forces act upon one another). Including human nature. Having a zen attitude helps, but nobody is so zen that nothing ever bothers them.
Deal with things the way they are, instead of pretending that things are the way you want them to be. It’s better than having your bubble burst at an unexpected time.
