We have sacrificed many things in order to pursue Perfections and to perform good deeds. So keep your tolerance, and be patient with the naysayers.
Always strive to improve yourself. Examine yourself and make improvements where you see flaws. The self improvements you make in this lifetime will benefit you in your future lifetimes. If you cannot correct your shortcomings in this lifetime, you will have to keep correcting them again in future lifetimes.
Putting improvements off to the next life is not the right attitude. Change for the better now.
