Do You Love What You Do?

I have just returned from a short trip to Chicago and did some touristy things there. Among the tours, I visited a Cubs game at Wrigley Field. The second oldest baseball stadium, it has always been a favourite of mine and I am very thankful to have an opportunity to see it live.
There were many thinks I noticed there that day, but one that really stuck out that was unexpected was the staff/ushers. They were all older people in their 60's or 70's, and it was obvious that they all really loved what they were doing. I assume they get paid for their work, but I'd be willing to be that they'd do it for nothing if they had to.
It's fun being around people like that. Taking pictures, escorting you to your seats, and selling concessions was fun for them. It made the whole experience that much more pleasurable and one of many memories I will keep from the day.
Does your real estate agent love what they do? Is it fun to be around them? Do they make the stress of buying or selling a house more fun? Good questions to ask!
