By not having an online portfolio to showcase my skills and be found by prospective clients, I simply focussed (subconsciously most likely) on building better and more meaningful relationships with existing clients and people I meet.
My experience has been very similar. I took down my portfolio about a month ago, and this past month has been the best business-wise since I started freelancing full-time back in May of ‘09. Is there a direct cause-and-effect relationship between these two experiences? I highly doubt it. However, my attitude toward how I express myself online has changed dramatically in the past 30 days, and I do believe that has affected how I interact with my clients.
