Welcome to the world of domaining. Hopefully, you are passionate enough to stick it out until your first sale.
I think you should have high expectations of yourself, but you should also be prepared to play the waiting game.
1. Domain investing can be rewarding but I think where many people go wrong is following the ideologies of other domainers. You should have discernment when it comes to the advice you take from others.
2. READ, READ, READ, READ, READ
3.Since you are new, the first thing I tell every single one of my clients is to take baby steps. Start small. Meaning only focus on finding that one domain that is high quality, brandable, and ready for someone to swoop up. Selling one high-quality domain name a year for $100,000 is better than trying to sell multiple ones for $100 each.
4. Make your domain name as valuable as you can. The more valuable the better.
5. Understand what makes a domain name special. Do keyword analysis, audience potential research, etc (or pay someone to do it for you)
6. Figure out who you want to sell to, as well as the market your domain name will fit into. That will determine the price tag.
There is so much that goes into not only buying a domain name but selling it. Most people fail by buying junk and buying lots of it.
Don't lean on your own understanding, find out what buyers want and give it to them.
