In much of what we do we are either creating or consuming. Both of these things can be time well spent or a waste of time. Often with creation or consumption you get so lost in it that you don’t even realise time is passing you by. But when you stop and see minutes or hours have gone by, how do you feel?
If you don’t feel good about what you’ve given you’re time to, try giving it to something else. Something more useful. Something more valuable.
