Solomon vs Books (What is your take?)

It has been said and it has always been implied that to be a good minister/leader someone must be well read. How does that gee & haw with what Solomon said under the direction of the Holy Spirit;

The Preacher sought to find words of delight, and uprightly he wrote words of truth. The words of the wise are like goads, and like nails firmly fixed are the collected sayings; they are given by one Shephard. My son beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh. The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man. For God will bring every deed into judgement, with every secret thing whether good or evil.

Ecclesiastes 12:10-14 (ESV)
