I say have fun with your other hobbies. You may be a little bored with astronomy right now. Your passion may return or it may not. And if it doesn't? Your fans will be disappointed - I love your astrophotography. You will still find something to make you happy.

I think WWII is absolutely fascinating. I've read many books on the subject. I got to combine my love of sci-fi and WWII with Harry Turtledove's Worldwar and Colonization series. Weird but fun.

Loving learning is the most important thing.
