Do you always sort your pieces?

So, do you always sort puzzle pieces? Is it a routine for you, or does it depend on a puzzle? I'm still new to Jigsaws and I sort my puzzles if they are 500 or more pieces. Lately I've been feeling that some puzzles may become too easy if you sort the pieces, especially if it's only 500 pieces and there's very clear and colourful sections in the picture. So I'm not sure if sorting is always something that makes the experience better! What do you think?
