"你放弃了你的童年。你错过了舞会、比赛、高中活动，有人说这很糟糕，我说那又怎样？这并不可怕。我玩得很开心。"

Simplified Meaning:

This statement talks about choosing a different path in life and being happy with that choice. The speaker mentions missing out on common school activities like dances and sports games, which some people think is terrible. However, the speaker doesn't agree and actually enjoyed the time spent doing something else. For example, imagine you decide to focus on art or music instead of going to parties. Some friends might think you are losing out, but you find joy and fulfillment in your creative work. It suggests that what matters is finding happiness in your own choices, even if they are different from what others expect. This attitude encourages you to follow your own interests and find joy in them, no matter what others think.
