10,000 hours of listening! Listen to how and what other guitarists play. It keeps you inspired, gives you ideas.
But ok you said make things easier. Ok for me that's about 3 things. Breaking things up, slowing things down, making things simple. If I'm trying to learn a song that's kicking my (_._) which does happen that's the process I follow.
First I'll try and learn the complicated bits one section at a time. This could be down to just repeating one riff over and over to get it right. When you're doing this, say the riff comes back to the main chord part - don't just keep repeating the riff over and over remember to play the chord at the end, then start the riff over. Why? Because it will get your muscles used to doing this. and you'll find it easier when you try and glue your broken up pieces together again. This applies to if one riff follows another too - play the first note of the 2nd riff then go back and repeat. My saxophone teacher used to make me do say the C scale instead of from C to C like most teachers... from B to D and it's not a bad idea.
Slow down!!!! If what your learning is still kicking your (_._) when you've broken it up, slow it down. Play it right slowly. Then gradually bring your speed up. A metronome is best for this so you keep the phrasing right (or lets just say the time between the notes). Again, gradually pick up the speed, don't rush.
OMG I still can't play this damn song! Here's where I usually simplify. This takes a bit more practice and some listening to know what still sounds right when left out, and what is really needed. Instead of playing several notes, play one note for longer, maybe bend or vibrato it instead. All else fails bung in some effects and cover it all up
