挺遺憾的。

Well, you are trying to balance your short term opportunity and a long-term investment.
我覺得你沒有CATCH 這個機會，挺遺憾的。
這年頭，找工，生官，發財不容易，有chemical的友誼 倒容易些。

General speaking, 職場幹得好的人，較為理性和professional! Perhaps, he values your leadership, people, or other skills. Or perhaps, you underestimate your ability?

A paragraph from Street Smarts by Hal Gooch
“To be successful you don’t have to be the smartest, the fastest or the strongest – you simply need to be alert to the opportunities all around you. Timing is often everything!”
