Pr 31:28 Her chilren rise up and call her blessed; her husband also, and he praiseth her.
The word blessed is sometimes translated happy.
She is blessed because she seeks God and His will for her life first. If you seek happiness itself, you may not find it, but if you seek God, happiness is often a result.

So basically, we need to be careful who we get counsel from or associate with. We need to put our trust in Christ alone. That one is so important that in just these few verses it is mentioned 4 times. We need to find our strength in Him. The joy of the Lord is our strength remember. We need to accept His chastening and learn from it and His word. Which means we need to spend time in His word. We need to have fear of the Lord and keep His commandments to us. We need to seek Him with our whole heart. Our hope must be in Him and nothing else.
