Trading is not for everybody but some traders do force themselves to get more from trading which can often turn out to go the contrary of the major aim of trading.
Nothing ever in life is for everyone or an all comers' affair. It's the same way every business has peculiar people who indulge them. However, the major problem with trading is that every Tom, Dick and Harry think they can go into it even without acquiring the basic skills for it. That's a bogus conception and that's why a lot of those who go into trading get burned out. Trading should be treated as a professional course like engineering, medicine, law, journalism etc and great attention paid to it.
What happens is that many people can understand that principle applying to other professions because they can see why they are so hard, medicine is hard but even if some could become doctors or nurses you need to also be able to deal with blood and stuff like that and not everyone can do it, in the case of engineering you know you will need a lot of advanced math and people know that math courses can be really hard, however trading seems deceptively easy, you just need to buy low and sell high and people think that anyone can do this, but we know this is not true at all.
