Don't live with regret. Live is not about money or fame, but happiness, wisdom and inner peace. Have you heard of www.theminimalists.com? A minimalist lifestyle doesn't have all the trimmings of the wealthy or the over achievers, but it can be just as fulfilling.
Wisdom and inner peace take work too. Understanding the self is most important but people confuse peace with inactivity and happiness with pleasure. Money has very little to do with this particular post.
