I try to adapt to my REI 1 on 1 clients.

In RE, you really need to be rather bold, outgoing, willing to take personal and financial risks, have the ability to communicate effectively, be personable with anyone for a short period of time to deal with them, be able to adapt and associate rules, laws and methods to varied opportunities and have a mature business judgment.
