I’ll take a stab at this. Being happy by yourself is about finding contentment and satisfaction with your life that doesn’t depend on external validation or reinforcement.

The first step is always going to be finding things you like and that motivate you. You have to take care to check in with yourself and decide whether the things you are doing are motivated by habit, by social desire, or by your own desire. The things you are looking for are the ones that fall in the last category. You’ll have to be honest with yourself to figure those things out.

Second step is going to be constructing goals from some of those desires. Not everything you like will be worth making goals from, but think about how you can make those things better and more fulfilling for you. Do you want to get better at whatever it is, as a skill? Do you want to share the product of crafts with others? Do you want to make it easier and more accessible for yourself?Figure out if any if these desires or activities can evolve to be more.

Third is making changes in your lifestyle to match. Reorient your life to your motivations. Figure out how to balance working towards your goals and indulging your whims. This is where the happiness and contentment on your own should be. If you are doing things you love regularly, and working towards goals that you want to achieve, that should bring a sense of fulfillment and contentment that doesn’t rely on other people to support it.
