Need some advice

Hello. Im 19 and have been playing baseball since I was little. I have played every position but pitcher. I have thrown some bullpin at practice to help other catchers and I know the grips and throwing motion of a few pitches but no real experiance. I was wondering where I go in my journey to become a pitcher. I need some advice as to what my first steps would be. Any advice would be helpful.

Be able to command your fastball…you have to be able to throw it to both sides of the plate…after that start working on your off speed pitches

Ok. I can throw pretty gud cause a fastball grip is what we were told to use when throwing to first. Whats a gud speed to have when starting?
