Chopin at 90 years old

My Dad turns 90 in a few weeks and he is my hero. 

We went to visit my parents today and after a while Dad announces that he is going to play us something on the piano.  He proceeds to play a beautiful piece by Chopin.  It literally brought tears to my eyes.  Dad has always played piano but has never considered himself a pianist.  He always said he knew just enough to get by but doubted his ability to be really good at piano.  He is really just being modest - he is the organist at church and has been for the past 20+ years.  It doesn't come easy for him and requires a lot of practice but he is good at it. 

Apparently last week he decided that the beautiful grand piano in his house shouldn't go to waste and should be played every day.  He wants to develop his talents and not just be satisfied with his abilities as they currently are.  So at the age of 90 he has started playing beautiful music by Chopin and who knows who else.  At an age when most people really start to slow down he just never seems to stop.  He has finally started to age a bit but what that man manages to do each day inspires me. 

If at 90 years old he can decided to play Chopin and further his musical talents what should I at only 35 be doing each day to further my talents? 

My Dad taught me an important lesson today that I hope to never forget.
