1. Passion - Everyone loves and is attracted to passion.  If you're not, find another job.
2. Planning - If you don't you will fail.
3. Organized - You know how easy and productive your life is if you are; if you aren't...good luck.
4. Efficiency - Use every tool available to source clients and candidates.  Your competition is and if you don't, they will win.
5. Honesty - To yourself, your clients and candidates.
6. Flexibility- Like Bruce Lee said, be water.  Water can flow through your hands or cut through the toughest rock.  Be water.
7. Compassion - Remember, you aren't selling pencils.  These are peoples lives and they depend upon you to advise them; not simply issue an invoice.
