I'm afraid of the drawing journey

Hi, I am a 18 year old boy that just got back into art and am interested in getting into furry drawing. However, I'm afraid of the journey ahead and how long it will take with, anatomy,details,color palates and charcter designs. I been having thoughts on if I will ever exceed my full potential and how to stay dedicated with out procrastinating. If anyone can help me by giving me tips or advice. It would be helpful 🙂
