What did you realize this year that you didn't realize before?

A friend quit her job in March. She said many people are living the same life after quitting: traveling, playing, etc. She thought all of this was meaningless, and I agreed with her at that time. I felt that traveling is often an escape and can't solve any real problems. But later in the day, I also saw another friend who had been traveling for four months and was still going strong. I could sense the vitality in her. A thought suddenly came to my mind: happiness is inherently similar. Happiness itself can be the meaning.
