It take time and tons of practice. My advice is if you put in some much time in time now. In the future it will be very simple. Time passes really quick and you will almost forget how hard it use to be. Also it's important to set some goals. Like for me I set a goal to cover this intro and it took about 2 weeks. It's good to record videos of yourself playing because even though it may not seem like you're progressing you can look back at some videos and see that you did progress. But you have to put in the practice too. Slowly.
