Say you make $8000 a month...$400 a month in (unnecessary?) fees is 5% of your gross.
Put it another way, would you be happy if there were additional monthly taxes on trading profits and losses of 5%?
I wonder how many traders here made money during Jan. Bear in mind it was a cracking month for the stock indexes. I bet there were quite a few who lost money.
Happy means an emotional state. Research shows the main drivers of being happy are sex, sleep and food (not necessarily in that order).
Rich alludes to material wealth and is obviously what the OP is referring to.
You have to define 'rich'. What is rich to one person is not the same for another.
You may also want to ask whether you want to become rich in the first place.
