Be aware of everything!  i know it's alot to ask, but that is our goal. 

When on a schedule (be it travel, work or just life) being aware of sunrise & sunset times, moon cycles, which way is north & tomorrows forecast just for starts, is vital not to mess up chances like this.     On my current photo marathon, i'm taking photos for 11 books in 35 days! yes, just 3 days per book.

I really enjoy the fact that being a photographer keeps me aware of so many things.  Think of it as an opportunity not a hassle.
