If one can track good tunes in a few days, that's extremely good for him/her, but I doubt that a few beginning artists can manage to learn to track even as soon as Eagle did. So if your tracking doesn't seem to work in a week or a month or a year, but you're still having fun, then keep on doing it!
True, effort and insistence on this is what let you improve.
I remember the first time I tracked. It was a couple of months after I discovered the tracking world, shown to me by one of my friends. I was really eager to track my first song (a cover, actually).
I didn't have any clue about this stuff; I was only given Modedit 2.0 and I went straightly for creating my first MOD. I thought I did it pretty cool because I was really satisfied at that moment with the results.
Neverheless, though I wanted to track more songs after this one, I found myself without a "hook", I didn't know what to track. I did track more songs, but I didn't feel quite at all proud of these songs. It took me some time to track something that really satisfied me likewise or more than my first mod. If I hadn't put more effort in training myself in tracking and gaining insights from other author's songs, I wouldn't have gone on tracking.
