Other than that just obsess yourself with learning everything you can about a subject. Read at least one article every day if you can.
I have my degree already, but honestly universities are elitist as shit and don't even need to exist in this day and age when all information is freely available on the web. Some day I hope our civilization realizes this. You still might not be able to get a job that requires a degree, but if you're familiar with how things really work, that will help you a lot in life.
