I have smelt roses during my younger days so is time for me to save as much as I can before turning 50 so that I can step down to enjoy life while still not that old. Also I do not want to be at risk of smelling sai if 1 day I am to be replaced by FTs.Don't mean to be rude, but although, you are saving 70% to 80%, you are living a terrible life? Life is about the journey, about smelling the roses. If you are so careful about money just for higer savings and retiring at 50, then you are missing the point to life.
From your expediture, you sound like a single. Correct? If you have kids, there is no way you can spend so little
I do not support people who have a lot of money but retire at a too old age, by then they will have no more energy to use the money.
