Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless.
Moral improvement (or perfecting) require an evolution leading to a higher consciousness, which is the true torch of life; it is what we have failed too much to appreciate, and that which would be fatal to fail to appreciate any longer ("pluslongtemps", Fr.); For if we do not take it upon ourselves to remedy in time to the moral colapse (or bankruptcy) that already threaten, the whole civilisation will risks to disappear.
It's great when people appreciate your work, but I don't know how seriously to take it. The amazing thing is that I found something so early that I can support myself doing, and that can even be extremely lucrative, but I love it either way.
I know for sure that appreciating whatever shows up for you in life changes your personal vibration. You radiate and generate more goodness for yourself when you're aware of all you have and not focusing on your have-nots.
