It take month if that the case!
Yes, properly creating music (or art) can take a long time. The record I'm currently mixing took 6 years to properly arrange and record! But when it's done I will confidently be able to say "this is exactly what I wanted to release" with no excuses.
A friend of mine recently recorded a "live off the floor" album in a day. Recorded, mixed, mastered, all in about 16 hours. His band was tight, and he wanted that raw feel. Part of me wishes my project felt right in that manner, but mine is layered and I performed 90% of the instruments. So it took what it took.
If you rush it, it will almost never sound "complete." This stuff takes what it takes.
