What psyhologist should I read?

Apr 2021
I love studying psyhology. But I always worry that I am getting no benefit of studying it and that It is just pointless. I also found out that Sigmund Freud and Carl Jung were ''wrong'' and that most other authors are or will be proven wrong. I really like studying works of psyhologists that experienced horror in they're lifes, people like Viktor Frankl and Fyodor Dostoyevsky. I feel like they know what it means to be human whilst other people are just assmuing and making theories that sound good but in the end prove to be false(like Sigmund Freud). I understand that Freud's and Jung's psyhologys really helped people out but I just don't know what to do. I am also curentlly reading Thinking, fast and slow-by Daniel Kahneman and at page 188 he says that psyhology can't be learned and it is just a waste of time. So what am I to do?
