Regarding books: the older, the better. There's a reason they're still around. Read the classics. Other advice: consistency is key to be good at anything. It's better to do 5 or 10 minutes a day every day than once a month for a full day. Other comments in this thread mention therapy: i had a very mediocre experience with therapy and think a lot of therapists dispense advice that follows cyclical social trends. If you sense this, run. It took me a while to realize this. Also I think most people wouldn't need therapy if they ate right, exercised, had a half decent job and had a handful of close friends/a spouse they got along with. This might sound cynical but i think a lot of what people are missing can't be replaced by therapy. Some things can be resolved but most can't and you just have to be constantly improving as a person.
