Congrats on understanding the power of real estate at such a young age!
I only discovered Wholesaling in my late twenties and was still considered young in the industry so you're ahead of the game.
Here are a few pieces of advice:
Wholesaling is all about SALES, pick up a sales job while you study wholesaling. Even part time works, part of the reason I'm doing multiple deals a month is because I worked nothing but sales jobs my entire life. Understanding the psychology of it all will help you tremendously.
Study, Study, Study - Study communication, Real Estate, Basics of Law, Time Management, Sales, Business etc. - Use podcasts and books to level yourself up
Books I Recommend - Secrets of the Millionaire Mind, The Compound Effect, The One Thing. Although these are not wholesaling specific, they will help you understand what it takes to make it in this industry.
Be intentional with your daily activities - Make sure that your friends, things you watch, decisions you make, etc. all lead to your success. If it doesn't add value to your journey: DROP IT.
To summarize it up, be obsessed with the process not just the end result. Watch every video that you can on YouTube about wholesaling, listen to the biggerpockets wholesaling episodes religiously, read often and focus on becoming a better version of yourself daily.
Best of luck!
