For me James 1:5 is my life verse. I always feel I lack Wisdom and ask God for it often. To me, this combines Psalms 119:105 because many people read the Word and gain knowledge but do not apply it. I may use a different definition of Wisdom.... Wisdom is knowledge properly applied. So you can have a lot of knowledge and still not be wise. In the US we have a lot of highly educated people who are still not Wise.
