I think it's too simplistic to see it that way....if you take as an example successful domainers that share their business tips, their sales, that are usually interviewed and seen as a reference within the industry......I don't think that means not to achieve anything. In my opinion, that's what success means, since they enjoy what they do, make money from it, and are good at it...what else could you ask for? And if domaining becomes a business that allows you to be independent enough...you can work from anywhere, travel, learn other things and have new hobbies...then, when your grandchildren ask about what you achieved...maybe you could say "Many things: freedom, being in control of my life and my time, getting to learn a whole lot of things and discover great cities and places, becoming totally independent and being able to master one of the most difficult activities that can be done online (domaining)..and I love what I do, that´s what I achieved". At least I would be happy for it.....its more than enough...
