Time is money. Kind of.
Spending time is like spending money. You should think carefully about what you spend it on, particularly if you don't have much.
Saving time is like saving money. It gives you a little more to spend in the future (please do remember to spend it).
Investing time is like investing money. You do it in the hope of future benefits (it doesn't always pay off, and that is OK).
You can't borrow time like you can borrow money, though. So do make the most of what you have right now.
Don't go passing time, you wouldn't do that with money. Don't waste it. Spend it.
