"他人がどう思うかに関係なく幸せでいることを恐れる人が多いと思います"

Simplified Meaning:

Many people hold back from being happy because they worry about how others will see them. They might fear that if they show their true joy or follow their own path to happiness, people will judge them or think poorly of them. Imagine a person who loves singing but is scared to perform in public because they're worried that friends or family might laugh or think it's silly. Instead of enjoying their passion, they hide it away and miss out on doing something that really makes them happy. This fear can stop people from living their life fully and feeling true joy. It's important to remember that everyone deserves to be happy and that worrying too much about others' opinions can prevent you from enjoying life. Try focusing on what makes you happy, not on what others might think. In doing so, you'll live a much more fulfilled and joyful life.
