The most important thing in life is yourself.

I'm not saying you should be wholly selfish, but you shouldn't be wholly selfless either.

"Love thy neighbor as thyself"

If you don't love yourself first, can you really love others to your fullest? Or in the context of your post, if your wellbeing is not the most important thing in your life, are you really able to do the best job at providing utility to others?

Too many wealthy people neglect their own wellbeing in the pursuit of providing utility to others, only to find themselves miserable later in life or die young due to poor health.
