Hey

When I started I was very regimented, I gave a few minutes - up to 10 to each activity and had a little plan I worked off each day. Since then I have heard that its not about the time given to an exercise but how many times you practice the specific activity. For example if I were to practice the E minor blues scale, instead of allocating 5 minutes to it, I would repeat 10 times in each positions. And this is what I actually do now, if there is a lick I am trying to get up to speed I will give it a go for a number of times and then move on. Eventually I will get it.

I think songs are important, and I would suggest that at least half of your time be put towards learning a song. Now that I am a bit further along, and this morning is a perfect example, my entire hour was spent on 1 song. And the rest of the week will likely be the same until I have it down.

What I have noticed is that for me there is no straight line. Its more of a zig zag, two steps forward and one step back type of thing, but I always go back! Some lessons are so difficult I have to break away for a time, and then continue in a few days. 

So I am assuming you are were I started - knowing nothing. It would be helpful if you don't already have it, create an activity list for each day and allocate a small amount of either time or repetitions to each - again spending most of your time on songs. 

And lastly, here is some bad amateur advice: I don't do warm ups. I used to, but an hour goes way to fast and the rest of the day will not wait!! (I block in an hour before work each day btw)

This is a hobby, it doesn't pay the bills. I just open my guitar bag, get my play list ready and start, finish in an hour and put it all away to start my day.

Best of luck

Bill
