Making peace with my success

I want to make peace with my level of success. I am successful in my field, but not as successful as I initially set out to be when I started. In 5-10 years, I will likely be at that level that I’ve wanted to be at my whole life. I would love to stop feeling tense about it now. I judge myself for not being more successful, at a younger age.

If I were ultra successful, I would be thinking –
Wow, I did it! I am so awesome! I knew it! I am without a doubt successful! Everyone would agree I made an impact! I obviously matter! I have fulfilled my purpose. Whew, now I can relax a little. I did it!
I would be feeling-accomplished, proud, beaming, Successful. Relaxed. Complete.

Should I try to think those thoughts now?
I kinda want to just stop romanticizing the future success and just be happy with the success I’ve already created, while trusting I will keep creating more. At the same time, I am hesitant to do that, because of old beliefs that “wanting it really bad” will push me into action, and I’m scared that if I relax I will never create what I want. BUT I am learning in scholars that the Feeling of striving does not actually make us take sustainable Action.
Can you give me some insight here? Thanks!
