If I look out my window right now, I can still see the last faint strains of this rainbow:
I love the bright colours against the dark, ominous sky. If you look in the to right hand corner, you can just see the secondary rainbow behind it. I am choosing to take this as an omen that I WILL get lots of productive thesis work done today, in spite of being in one of those “I feel like I can’t do anything” slumps.
Please feel free to link to your own “good omen” pictures in comments, and explain what they mean to you. 🙂
