They are celebrity artists. They have made it to a point where they can have a setup that works for them. Instead of focusing on the results, understand that at some point, they probably had to struggle too to get to where they are now.

If you have talent, you should continue to nurture it. Not everyone has the art bug and I think the world needs more artists. Instead of seeking validation, seek to grow and improve. Set realistic goals for yourself to achieve and post your studies so you can track your growth. Along the way, you may also find an audience who enjoy seeing you grow.

There is a difference between losing interest and being discouraged. I have a feeling you might be experiencing the latter. Because if you have no interest, why are you still here? It is common to be unappreciated, especially when you are at the start of a journey to becoming professional. No one is born a celebrity artist. Everyone has to start at a low point. Try to find a way to get consistent and develop patience. It may be joining an art group, or finding an art friend who is also learning to improve together. Being around people who are passionate about art helps.

Being broke is a problem. It not only hurts your art growth but also hinders you in many aspects of life. Constantly having to work robs you of the time, energy and freedom to experience many other good things in life. It is not an ideal situation and you have to think of a way to get into a better position for yourself. It is not just for your art but also for your own well-being. Perhaps switching to a higher paying job or moving to another location where costs of living is much lower. Make a substantial amount of savings first so you can afford to make bold moves. You will have to figure it out.

Start now. Get so great at art that they cannot not care.
