"I keep asking myself can I make a living selling domain name only? I have the will so, I just need to find the way. Who is willing to mentor"
I'm wondering if you really do have the will? Usually, I find that people who look for a mentor early on, don't have a go-getter type of work ethic. It's usually wanting somebody to take them by the hand and say do A, B and C and you'll have success. If you could only see my Domain folder and all the text documents and spreadsheets I had when I first started. Folders just for keywords. More than a handful titled Domain Notes, Domain Tips etc. Endless scroll of notes I took, etc. I get tired just looking thru them all, lots of late hours trying to figure it all out.
There are people who do this for a living, so yes it's possible. What's the difference between them and you? Sometimes it's money. Obviously, it helps to have some, because you need to buy domains. Work ethic of course. It takes more than that tho, some people think just working hard will do it. You need to be somewhat smart, be able to grasp things, like the market, possible trends, learning from your mistakes etc. We are competitors.
Having said all that, you really don't need a mentor, because while being competitors, you'll find people willing to help each other out with questions and problems when they arise. So you can always ask questions, after you put in the work and can't figure it out on your own.
