I would argue it's even easier in the evening, for sure. The point of doing it in the morning is that your brain is fresher; I'm just saying that might still not be enough to start.

Yeah, but it's after work, when you're inevitably more tired. One could push it by going to bed earlier and waking up at 5am, but it risks becoming unsociable.
Also, I expect you (and OP, and a lot of folks in this thread) are 20-somethings with no attachments and no family. Those things tend to suck every bit of spare time you have, for years on end.
