I agree, to me success would be feeling happy maybe 50% of the time or at least feel like I was pursuing happiness. But it seems to be more difficult for me to define that than many. I have tried a lot of things mentioned here, such as learning a new hobby or going to some sort of activity focused meetup. After a while, I feel I am grabbing at straws. I grew up in a very functional household, without a lot of love. My parents both worked, and it seemed to me and people who had been to my house, that the whole family walked on eggshells around my dad. I am an introvert, but for some reason my dad didn't really have a 'boys will be boys' mentality. He had more of a "the only good child is a quiet and still one". My parents didn't socialize much with anybody, and it led me and my brother to believe that everybody is defined by their work, and that is the most important thing in life. I realize this is a fallacy and I battle my habits accordingly every day. In public my dad would not let me embarrass him, and he would direct me around with his hand in the small of my back. It created a feeling that I am always in the way of others, and I can't shake it. I also want to kill myself if I get embarrassed over the smallest thing. It has really damaged relationships for me(along with my anxiety). But I have always been functional; able to get good grades, hold down a good job, etc. Its a really scary feeling to believe that you are messed up and incapable of enjoying simple things in life. I guess I just want to feel like I am a part of something, and I never really have felt that even in my own family. My whole definition of what it means to be 'a part of something' could be unrealistic.
