That is the key(no pun intended) to it, just enjoy what you are doing and just see how far you get. Listen to good quality music and dont try to overdo the learning process. Lots of traps to fall into as I'm sure your teacher will tell you. Lots of folks learn musical instruments in their later years.
They tell me it delays the onset of Altzeimers

But the way I act somedays I'm not so sure
Just dont try to play jazz right away, I've been trying all my life and still lousy at it

Bye the way, I have hands like shovels and it has done nothing but help me in my life of playing. No problems stretching out to these bar chords and runs that hold back other players.
