Hedonistic tendancies teaches you to want more and more, you never appreciate what you have because once you have got it you want the next thing. It becomes a zero sum game and you've probably just sacrificed a whole heap of your precious time and health to achieve it.
Many people fall trap to trying to beat others in what they have / what they do.
They see their friend has a bigger house, they want a bigger house.
They see their friend had a big weddding, they want a bigger wedding.
They see their friend earns X a year, they want to earn X + Y a year.
Remember, there are 7 billion people on the planet, you will probably not be the richest ever, so learn to be happy with what you have.
This is not to say do not strive for improvement, just allow yourself to be happy.
