If you do not own the web address for your own name, or variations thereof, go to Go Daddy right now and reserve it. This is a great babystep to get started. Reserve yourname.com, yourspousesname.com, yournameconsulting.com, theyournamegroup.com, and on and on. Even if you don’t use it right away, it’ll serve as a placeholder. For $10 a year.
Whether you like it or not, you are a start up. You are a company, a practice, a web site, in alpha phase. You are in development phase.
Today, you’d expect any viable company to have a web page. Do the same.
