You're right, but I like to say that just to to make sure people with depression don't redirect their problems towards something else, like politics or people.

I used to blame many things for my problems, including me. I kept thinking about that "positive" mentality, for a long time. It can start to make sense at one point or another. If you're depressed, I think it's important to have a minimum of knowledge about questions on the meaning of life or something like that. If it can make you think in a healthy way and prevent people to turn into stupid things, I don't think it's really insignificant.

Good life philosophy can help you make better choices. I'm not talking about religion, I'm just talking in general, how do you look at the world.

I agree that philosophy won't really help, but it would be stupid to just not talk about it a little.
