Hi DamnLag,
In my opinion, the most important factor is freuquency of practicing. Can you put in ten minutes a day? And then on some days, try to sneak it some more time?
My reasoning is this: You are training your hands to do all new things they have never done before. The more frequently you remind them of these new moves and skills, even for just a few minutes, the more quickly those moves and skills get absorbed into your 'physical memory', where they become more second-nature.
Of course people who have an hour or two a day have an advantage - but so what.
You want to learn to play, and you have the job that you have, and so it is just a matter of finding a way to allow even just a little time for your music as frequently as possible.
If music feels important to you - then it's totally worth it to work it into your life, even in small doses.
My two cents! - Lisa
