Since I was very young I've been hearing the idiom "ser un somia-truites", which literally means "to be an omelette-dreamer". It is used to explain that someone is too dreamy, not focused on the real world or the important things. It is quite similar to "to be a daydreamer". I have been accused of being an "omelette-dreamer" some times, and this is because I have many crazy-like ideas, maybe not very realistic, or difficult to put in practice. However, more than once I have proved that it was actually possible to make that unrealistic idea became a reality. This is why I love so much that expression: to me it is like they are challenging me. Otherwise, there are many things I wouldn't have even tried to do.  So every time I have a crazy idea I call myself an "omelette-dreamer" (if there are no volunteers), so at least I try to make it happen.  Because everything that has somewhen been done, had previously been an idea or a dream. 

Answering to Lindsay: Well, when choosing the image maybe I focused more on the feeling that the idiom transmits to me, rather than an illustration of all my explanation, and the final result it's quite confusing... The thing is that, to me, all that self-challenging and the belief that everything can be done is even relaxing. It always made me feel apart from the others .It's not too good in the beginning, but you can always try to be optimist and make the most of every situation. So, maybe this image makes more sense: http://jv.gilead.org.il/rpaul/Autour%20de%20la%20lune/images/038.jpg It's an illustration of a book by Jules Verne. He is actually the reason why I am a daydreamer. And Deb, I didn't know that artist, but his work is interesting. I love the paintings I've seen so far. Thank you for the link!
