does self-help really helps? depends

this video is made for the purpose of education (learning logic)

sometimes at schools, teachers teach self help, but teaching kids how to be happy and treating them as unhappy is like trying to teach a pro gamer at a tournament how to play games and treating them like a noob, as a result, most (not all) of their students become unhappier, see how we humans don't actually want to serve others, but instead steal energy from others by nature? how does it feel to know you're selfish, i am too, we all are

depends
