Had the same feeling. Talked about this with my wise elders in my native hometown. Here's what they said - " Comparison is the thief of Joy. You have achieved everything you want in life, and yet you still aren't satisfied or happy because you are comparing yourself with someone whom you see as a person living a better life than yours, even if it is the future version of you, that you wish to be. The desires are endless. No limits on wants in life. You can only become happy when you take control pursuing wants, desires and comparisons all the time. I don't recommend you stop doing them completely. They are crucial for you as they provide a purpose and motivation to live a better life, but they alone shouldn't be the driving force. Start doing this and see how your perspective of your day to day life changes. How your heart and mind starts to feel lighter, clean and clear. How this brings you peace, calm and eventually satisfaction and happiness."
I've tried my best to translate what they said in my native language to English. I hope this helps.
