I'm going to play my guitar during the daytime
Why do you need to practice so much?
I'm too tired to practice at night.
That seems like a fine trade off. Just keep practicing and it'll start to come together.
No, I mean that I'm going to practice during the day instead of the night.
That is fine that you want to change around your practice schedule. I think that it is acceptable to practice if you are trying to get better at something.
