Trading is tough, no doubt about it. And because it's tough, the bigger the reward if you're successful.
Like any difficult occupation, trading favors the people willing to put in the work. Why trading seems to be really tough is that there is no set courses or a curriculum or a knowledge test like you have with other occupations like doctor or lawyer, etc. You determine what you need to know and/or what to do. So trading will naturally favor the self-starter, the go-getter, the person who thirsts for knowledge.. and the person who has financially set themselves up for going years without the need to make money from trading.
If you are emphatically chasing the knowledge and experience over money, you have the right mindset to succeed and will succeed one day if quitting is not in your vocabulary. So ask yourself, what is more important to you...the attainment of knowledge or money??
