Why not? Making guides should be fun! :-D Which one were you planning to do, a main highlights type escapade or an EP type full guide? I like the latter better.
If that's the case, just take your time and work day by day, it's not at a rush and you'll feel liberated when you finish. I know my first guide took two months to complete, and my latest one was 3-4 weeks, but it went by easier by pacing yourself and breaking everything down.
