“Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding” (PV 4:7)
Somebody gave me this advice long time ago. It has been useful to me all these years. It will be wisdom of life to you too! Never forget! This is the order of importance starting with the greatest:

1-Your relationship with God! (Know God!)
2-Your relationship with yourself! (Know yourself)
3-Your relationship with your spouse! (Know your husband/wife)
4-Your relationship with your children! (Know your children)
5-Your relationship with church people and your co-workers
6- Your relationship with others!

This list must be in this order! Once you switch the order, you will fall into trouble! For example, if you love your children more than you love your wife, you will fall into trouble! But the most important thing to remember is this: God first! God first! God first!
