There are many ways to think about setting priorities. Let look at several ways and then get direction from Matthew 6:33.
1- Must Do, Should Do, Could Do & Can't Do
2- Important, Not Important verses Urgent, Not Urgent
3- The One Big Thing
Matthew 6:33 (NKJV)
But seek first the kingdom of God and His righteousness, and all these things shall be added to you.
