No you can't.
Well, you can, but you aren't going to get any work from it.
If you teach yourself a trade, you could become the best in the world at it but you still wont get a job because you don't have a certified piece of paper saying that you can do that trade.
People don't care about your skills, they care about being told that you have skills.
Lol you're kidding right
I'm certified in the same exact software my mom uses for her work and I create the same stuff she does. College didn't teach me that, I did that in highschool, as something extra cause it was free for me.
My mom didn't get that from college, Adobe didn't EXHIST when she was in college.
Hell, my mom's degree is in art, she works in a communications job.
Her degree has little to no effect on her job.
A college degree is not impressive nowadays, because look at how many of you want one. You will all be identical. The only difference will be what part-time job you worked to pay for college.
YOU have to show the world "I'm a blacksmith and I can make an awesome looking sword," then you PROVE it. A college diploma does not show that you are worthy of a job. Just that you studied how to do that job
