I love using similes!
I was very tired late at night one time and was brainstorming some... One of them looked like this...

What is your favourite simile and can you have too many? I sometimes think that if you have too many, it interferes with the flow of the writing. Opinions?
I once heard a writing teacher say that people almost always have the opposite problem of not using them enough. I understand they are hard to overdo.
But, you asked how people think them up. Every now and then I think "I should probably use another simile/metaphor thingy about now..." So I keep my eyes peeled for an opportunity. If none pop out at me, then I burn some energy thinking one up. It may not stay, but it is good practice!
