Well congratulations and it is as the others say. The fun is only starting. Even though learning to play the guitar is something quite a struggle it is soooo incredibly rewarding to actually finally achieve something. For me it always helped that I was over ambitious ( wanted to play really complicated stuff ). That is still my motivator today that I want to achieve those goals, and knowing for me which songs I wanna learn in the road towards my goals.

The way I learned to play scales was only with the help of the CAGED system ( each position of the scale linked to another chord-shape ). With help of that I figured out the root / key and figured out all notes so I could make up my own chords. The piano is really usefull for this, helping shape those chords. But the if you can count for yourself it might even work better to learn how big an interval is to see which kind of chord you are dealing with ( major/minor etc. ).
