Whatever you have, you must either use or lose.
Sentiment: NEGATIVE
Use it or lose it.
So how can you lose what you've never owned?
I've still got it. I refuse to lose.
If you lose who you are, what do you have?
I don't want to lose what I've won.
You must lose everything in order to gain anything.
Use it or lose it is a cliche because it's true.
For everything you have missed, you have gained something else, and for everything you gain, you lose something else.
Take what you can use and let the rest go by.
It's not what you've got, it's what you use that makes a difference.
