I guess one could always improve--I hope I'm not constraining self-improvement in any way
--but then, I think: if it ain't broke, don't fix it. There are people who are always seeking perfection, never find it--and, thus, are never happy. As a result, they are always in a "crisis."
--Then again, as I think further, It seems that, possibly, my advice would have the effect of constraining you from evolving further.
The best answer, in this case, might be:
I would be content with what I have--but, amid that contentment, I would seek to evolve to a higher plane in all things.
I think there's something special about you--and that either you, or those you raise, will do great things in the future. I can't put a finger as to why--I just have a gut feeling.
