"Have fun, keep smiling and always do your best!" This is the message that I tell my two young sons every day before I leave the house. It is also the mantra that I follow to the best of my ability. It's like Nickelback's new song "If Today Was Your Last Day" where he says "Leave no stone unturned, leave your fears behind and try to take the path less traveled by".
When I'm looking for a specific property for a client I leave no stone unturned. When I"m calling apartment building owners to see if they want to sell I leave my fear behind (actually, I left my fear behind two decades ago on that onee). When solving problems and negotiating on behalf of my clients I sometimes take the path less traveled by to create new results.
When you are doing what you love, it's easy to do.
