Is ketamine going to make it less depressing that you work in ad-tech? Why not also microdose magic mushrooms as you work in ad-tech? Why not buy from your local farmer's market as you work in ad-tech? Why not volunteer for a local organization in your free time while you work in ad-tech? The problem is that you work in ad-tech. No amount of microdosing or macrodosing LSD or mushrooms or ketamine is going to change the fact that you probably have no social skills and your life work in ad-tech is meaningless, and having slightly more money than the average prole and being able to afford drugs they can't isn't going to make you happy.
