Aside from fapping, but drinking and video games have been a big part of my life for the past few years. I've spent a lot of time on them and I know I've used them to escape from the world. I thought it would be good for me to give up all three, I think it will be easy enough. If I don't have these things to keep me distracted then I can accomplish more. Since I experimented with this, I found that I get a lot more done. I train harder, eat better, feel better etc... And the sense of accomplishment I get seems to give me a confidence boost, which helps with social anxiety.
