There are so many ways you can approach it so I am going to offer you two.
1) Most young people benefit from going to college and learning what they are great at. You will also learn to communicate and hopefully get a sense of accomplishment and confidence. You can learn a field, get a great job and start saving for real estate.
2) If you really believe you have the confidence and work ethic to start immediately, you have a lot of options. What @Remingtonlyman suggests makes a great deal of sense. You can also work as a real estate agent assistant and learn everything on the inside. You can also work for anyone with any real estate role and go from there.
One option is you pay money to learn a skill that will fund a real estate career. The other is you get paid to hustle, work for very little money, but get paid to work. Number 2 sounds easier, but it is much harder. The best advice I can tell you is that making it in real estate is not hard, but it does take financial discipline. Especially in the beginning. Everything you make should go toward future real estate purchases. All the best, I am sure you will kill it.
