I would have to say I read over 10 articles across various blogs daily, as well as posts from members on NamePros with news pieces under "
News". (Z.com was broken on NamePros here)
I don't limit myself to just blogs, rather sites like Forbes and the like as well. This shows trending products, etc. that could make it and have available hand registrations up for grabs (if you're quick enough and make a split second decision).
In addition to all of this, I read domain name discussions with trends and sales here. I research those trends and invest wisely.
Blogs aren't the only resources to look into. Learn from other peoples mistakes and get a head start.
I've made plenty of mistakes, but have recovered myself.
The more you read, the better you can implement a plan for yourself by using pieces that worked for other domain investors.
There is no reason why you can't spend 4 hours of your day reading and 4 hours scouring for your next investment if you want to turn this into a full time lucrative job.
