Yep, more things to not forget.
I have to remember this one myself at times.
It's ok to take breaks from things, it doesn't mean you're giving up* on them or quitting entirely.
*Unless you are. In which case don't*. ._.
*Always, ALWAYS, come back from your break. Else you really just gave up and then lied to yourself about it. >_>
When you feel like you're grinding into a wall of stone, take a break. When you come back you might see a way around it, or you might now be equipped with a jackhammer. >:D
