I know Tommy Ga Ken Wan through a friend, he's a brilliant professional photographer who is based and lives in Glasgow and he recently did a talk at The Glasgow Art School for a Media Week about being a pro photographer and how he got there. It really inspired me to do more with photography as I would say it's definitely one of my main passion in life and I'd love to do more with it. Tommy gave a lot of excellent photography advice in just 25minutes of his talk such as these wise words he read some where... " The amateur worries about equipment, the professional worries about money but the master worries about light." The video of his talk in 50mins long, it's definitely worth a watch.
I would recommend a look at his flickr also :
