我想將讀書學到的東西放上工作上, 唔想浪費以前讀過的東西. 可是, 這工作不能給予我與人接觸的機會
In order not to waste what I had learned from school, I wish I can use what I've learned on my work (job). However, this (my present) job wouldn't allow me to do so.
I've put your 1) and 2) in same paragraph, because they are related. And, we don't have to repeat the first sentence
