I want to get a job instead of going college. How should I convince my family?
Sometimes you can't, but you can ask them to be patient with you. You can ask them to respect your decisions. You can show them how many people have successfully created their own education outside of the formal structures with which we are familiar.
If you are in the United States, you can also make a good case it's not a sound investment.
Probably the best thing to do would be to share with them your plan. What are you “Yes” planning to do. For instance, if you want to learn a new skill, show them the Coursera/Udemy/FutureLearn/Khan Academy learning plan and then how you will add value to businesses such that they will want to hire you.
Take this as your first test of marketing. Demonstrate to them how your years of business experience gained in lieu of college will actually put you ahead of your peers, and then figure out how you will market yourself for the jobs you want.
Last remind them they were young once too. Maybe if you go out in the world, and discover something you really do want to study, you'll do that much better and be able to go so much deeper because you actually have some experience to draw on.
Parents just want what's best for you. If you can show them that you've really thought it through, and you believe this is it, they should give you some space about it.
