Good morning.
I have 2 pieces of advice to give you.
1 - When someone writes a book they are told to write about what they know. For example if you live at the top of a snow topped mountain it would make sense to talk about how cold it is living up a mountain. There would be many day to day challenges. However, it would be much more difficult to write about what it is like living in the middle of the Sahara Desert.
If English is not your first language then for now you should concentrate on words and phrases in your first language. What can you sell with the skills that you already have? If you are a chef or a baker then you will know that names relating to food in your language will be popular and more easy to sell.
2 - I started domaining with $200 which may be a lot of money to many people. This was 2 years ago. I now have 950 domain names. I receive about 1,000 views per month on Efty.com but I have only sold two names. I have received offers which I have accepted but I did not complete the sale for one reason or another.
If you are prepared to work hard and study and learn then you can achieve anything.
If I can do it you can too. You have to believe in yourself.
Start slow and make mistakes which is what we all do. Learn from your mistakes and don't make them again.
Enjoy your journey.
