R’ Moshe Sternbuch shlita (Taam Vodaas) would say: “'עם לבן גרתי - ותרי"ג מצות שמרתי' - What does Rashi’s explanation have to do with Yaakov’s plan to appease Esav? Why should Yaakov keeping mitzvos by Lavan be a reason for Esav not to hate him? What Yaakov meant is that what matters to me in life is mitzvos. Whatever wealth I have is important to me only because it enables me to do mitzvos, nothing more. I have no interest in amassing fortunes or living a life of luxuries. Therefore, you have no reason to be jealous of me.”
A Wise Man would say: “Investing in your health will produce enormous benefits.”
