A simple way I would recommend everyone is to do like what I do, go buy yourself a domain name! It's much more memorable when I tell people my email address is email@example.com or firstname.lastname@example.org! It makes you easily remembered and greatly helps in your own self marketing. You don't have to get a blog if you don't want to but it doesn't hurt to get your domain name first.
And the best part is that it's not expensive at all! Its not going to cost you hundreds a year, there are so many free options available these days and its easy for you to get it done!
Here are some tips from me
Anyway, do start thinking of self-branding yourself. Even if you don't want to use it yet, buy the domain now!
