I hold a Bachelor Degree in Computer Science, am interested in self improvement tools, health, politics, Austrian economics, metaphysics, finance, sale copywriting, and entrepreneurship.
One of my own "fatal flaws" is that I have so many interests, if I were to list them all, the list would be really... really... really long.
As I blog about things, I will sometimes link to products that I believe might be of value to others.
When I recommend a product, I might also try to be part of that businesses referral program.
I won't recommend something for the sole purpose of making money, but if someone else makes a sale and profits because of something I had to say, I see nothing wrong with getting something in return for having made the recommendation.
