To increase your quality of life, think about what a happy, satisfying, fulfilling life would be like, and pay attention to how you would have to show up to have the best chance of creating that life for yourself.

The more you act like the kind of person who has the life you want, the more likely you'll do the things that kind of person would do, and that will lead to having those things in reality. By noticing how you are already like this ideal version of you, and by recognizing where you need to focus your energy to build the resources you need, you can grow into an enhanced version of yourself, more capable and more attractive, which leads to a better quality of life, by your standards.
