Not at all.

Growth, as we mean it, is a positive thing. It isn't a value statement that you are inferior as you are and only through growth will you have value and be acceptable.

Accepting (and loving) yourself for who you are is seeing that you have innate value with all else stripped away. It doesn't matter if you never grow, or in fact, if you decline (as we all do, if we live long enough). You see that you still have worth despite this. You have your lifetime of experiences, your hopes, your dreams, that which makes you who you are.

Growth is one of life's biggest joys. Depriving yourself would be a shame. When you have accepted yourself for who you are and then srive for growth you aren't saying, "Once I have achieved X, I'll be more worthy of acceptance and love". You are instead saying, "Let me explore the heights to which I can climb in this human experience". You might epicly fail, but that is alright, because you are fine with who you are. On the other hand, if you are insecure with who you are and don't love yourself, then growth becomes a risky endeavor. Should you fail, it is further proof that you are an inferior person as you weren't able to live up to your ambitions.
