I'm in no way trying to discourage you, but I'll tell you a story. Back when I first learned how to ride, I took a class to get my license, and the instructor said "there are two types of riders; those who have had a crash, and those who will." I thought it was bullshit at the time, and I rode for years after that with no crashes (some close calls, though).
Then, in 2014, I got hit by a car from behind while I was stopped to make a left turn. The gal who hit me at 55 mph was texting and never even hit the brakes. I got a helicopter ride to the trauma center and a broken back, concussion, shredded elbow, and four broken ribs. My helmet and a bystander who put a tourniquet on my arm saved my life.
Do your dream, but be realistic about the risks.
