Chossid, to answer your question, look at the Rambam Hilchas Lulav 8,15 and the Magid Mishneh there ויעשה הטוב מצד שהוא טוב do the good for its own sake. See the Rambam Hilchas Teshuva 10th Perek. Pirkei Avos שכר מצוה מצוה the mitzva itself is its own rewards.
I totally agree with you.
Just if you can explain to me what does these quotes mean? Especially שכר מצוה מצוה?
