I commit as clean as possible, each one should be a functioning feature or a part of it. I try to do small ones, so generally they'll just be part of a feature I have on my todo list for the entire feature. That actually helps me to mentally move on as well. If I need to rename some stuff I might squash commits, but no wip commits in the actual history.

End of day I usually commit a "temp" commit with a few comments to myself and push that to the remote branch, revert that the next day and force push over it for the next commit.
