Some people in this digital age can, some can't, as is to be expected.
I first pondered this when I realized I didn't want to learn to use new input hardware for gaming. Or learn a new 'gamepad' setup or what have you. I had certain configs I was used to and didn't want to 'unlearn and relearn' control of this game or that.
Age certainly CAN come in to play but, as many other things, should not be used as an excuse.
Just keep on learning, unlearning, and relearning till you make 6 figures my friend, forget the others and put that energy into your own development.
Oh yeah, keep smiling :)
