Great, and very honest article. I love how you reflected on your own goals and motivations. It's always good to take a step back and see if we are driven by the goals and values of others or whether we are true to ourselves.

This article is a great start and shows your uniqueness and personality. Well done.

Well said!

And nothing selfish about writing for yourself, thus you always also write for others. But even if you would have a blogging diary, that's not selfish, taking care of your own knowledge is a gift, not a sin.
