The future is scary, I think everyone can agree on that!
I think it’s good to try to see being Competitive as a positive thing, use it as motivation and a means to see where your strengths and weaknesses lie- or even as a bridge to friendship! There are always going to be people who take it too serious and are elitists, but pppbbbbt on that.
It sounds like you know what you want to do- use college to your advantage! Find professors who are helpful, ask them what you need to work on, what books should you read outside of class, if they know any other students who are interested in the same things as you-
Find a good art program, if it’s at a college or local art center- find like minded people, collaborate, be inspired and supportive, elevate each other’s art to the next level.MAKE THINGS.MAKE THINGS.MAKE THINGS. There will be jealousy (it’s human nature) but if you’re a positive force, then you will have that same positive support helping you as well!
