I don't have to keep going, I want to keep going. Writing is something that I've decided to try to get better at and every article I write gets me incrementally better.
Re: siblings and increasing writing skill: there are too many blogs. Try writing in private and for literary (i.e. non-tech) audiences. You'll have better chances of focusing on the actual writing, you'll be able to branch out, you might get feedback on your writing.
