In Psalm 90:12, the psalmist reminds us that all of our days are numbered and none of us know how many we will have: “Teach us to use wisely all the time we have.” Therefore, we should all live as if the present day is our last. If we actually did this, would we live differently? We might:

Think more positively.
Forgive quicker.
Step out of our comfort zones and do that thing God has been calling us to do.
Start that new career.
Spend more time with loved ones.
Make more time for ourselves...  more
