I believe Grandma might be hinting at the fact that you almost seem to produce for the sake of producing, pushing songs everyday.
Now, there doesn't need to be anything wrong with that, as long as you're happy with them, but usually, writing a "good" (no offence, I don't mean that your songs aren't, just that they might get better if-) song takes quite a deal of time and thought.
I've been writing on my latest song for about two weeks now and that's far from the longest time it has ever taken me to compose.
If you think it would make your songs better, you could always try to think it through several times, both before and after finishing a passage, instead of just slapping something together and thinking "hey, that works" - it's always better with "hey, this is great!". Again I point out the fact that I have no idea whether or not you already work like this, and as long as you might be able to get the songs to sound as you want them in a day or less, that's just a great asset for you.
