If wishes were horses, then beggars would ride. No one but you can ever make the improvements to your life that you think it needs.
Here's a reason to sleep at night and work on music during the day: Your brain is a muscle, and the way you work that muscle is by making decisions. From what you're going to eat to breakfast and wear for the day to how you're going to react to that car that forgot to use its blinker when turning in front of you or how you're going to EQ that snare drum. The more that muscle is worked, the more it gets worn out and the less effective it becomes at making future decisions until it gets a chance to rest and stop making those decisions.
When you sit down at the computer at night, it will be more difficult to make decisions. Especially if you've had a very long day at school or work, and DEFINITELY if you've had a bad day. Plus, you end up staying awake and further stimulating yourself with sensory input until very late, losing both sleep and productivity.
Now if you make music in the morning, your brain is fresh and your mind is ready to create - and if you end up having a shitty day afterwards, you've already completed your music session for the day so you won't risk having an unproductive session or worse, one that doesn't happen at all.
