Playing with your hand NOT resting on the strings or body, using TPIMRp (little p is pinky), master playing patterns. Travis picking is popular. Boogie woogie is too where you play three notes together with PIM and playing the bass line with T.
A pinching pattern or claw hammer is another method. Once you’ve mastered (I mean, can play Eric Clapton and Co) it then take it into the minor keys and learn the directional flamenco picking. Where you flick RMI downwards striking your fingernails, following it with your T in a downward pluck, then pulling IMR upwards. Some people reverse this but it’s always the same when it’s repeated. Eventually you’ll be able to picado like a pro. Malagueña watch out.
Your finger nails are now important. Learn about shaping them with a filer or getting gel tips. Your girlfriend can help in this department.
As others have said, there’s no short cut, only practice and patience. Eventually it will click.
