Thanks to your blog post, I do realize that most selfish people become selfless when they begin to mingle with other people around them, as you said;
"As you will see many people using others and taking advantage of others, while you are not doing so, you are sound to your terms and you are known to be the survivor."

This statement to me seems you were only selfish because of lack of friends and not any other motives, just asking,
Is this true in all cases ?
No, I do not think one becomes selfish due to a lack of friends. Sometimes it is the opposite scene.
Truly, the world has not straight forward answer, thanks for sharing.
