1. The road of life must be walked step by step by yourself. What can truly protect you is your own personality and cultural choices. Then in turn, what can really hurt you is the same, your own choice.
2. Stop regretting what you missed. Only others will have the opportunity to meet the people and things you miss, and only you will have the opportunity to have them if others miss them. Everyone will miss it, everyone has missed it, but what truly belongs to you will never be missed.
