Jumping back into the business after being out of it for many years. Seems like a lot has changed and there is an overwhelming amount of information floating about. Seems like a lot of sharks too! As such, I thought I'd solcit input from all of you fellow domainers regarding important lessons that you have learned along the way. What's your best piece of advice, so a beginner doesn't get burned? Thanks in advance for any educational responses you can provide!
