Long story short, the more you shoot the better you'll get. Don't scrimp on lessons, you need to get the basics right, if you allow yourself to develop bad habits early, they'll be hard to eradicate.. a decent coach shouldn't let you get away with introducing bad habits.
Practice does not make perfect, it ingrains habit, make sure they are good habits.
You'll find that the better you get, the harder it is to improve.
Anyone can score 50,out of 100 after some basic instruction, you'll progress to 60s and 70s with some effort and so on, but moving from 80 to 90, and 90 to 95 takes a lot of time and money, commitment and talent, it's is something few of us will do.
When I miss, I stop, think about the technique, and execute it properly. It's amazing how much better you shoot when you do the basic things right.
You are at the start if a great journey, enjoy it, it will keep you both satisfied and challenged for years.
All the best.
