Like @DeaghlanNG said, it comes to you, but I think it can come faster!
Going outside, doing new things, traveling, or studying different things can help!

Last year I got inspiration during world history class about these apartments known as Tenements! All you gotta do is be patient, hell, maybe even take a break!

Yep, that's THE hardest part.
Thing is about inspiration is it comes to you, not the other way around. Be patient, you never know when it might show up.
