Keep your fingernails trimmed. Try to make sure each finger is only touching the string it's meant to hold. Callouses will eventually form and playing will get easier. Dexterity will improve over time.

Also... on YouTube, look up Paul Gilbert's Intense Rock vol 1 & 2. Do everything he tells you to. I found those after I had already been playing for 10 yrs or so and wish I had just started there.

Keep at it and best of luck!🤘
