Long time commitment only comes with long term investment. I mean, almost everyone works for his or herself, and defend his/her interest.

Loyalty is earned when you are able to attract the people who believe in what you believe, who share similar values as your firm, and you are able to help them to understand where you (the firm) are coming from, where you currently are, and where you are going plus helping them to cleary see a future for themselves in that journey.
