I know it well, right down to the overcompensating bit. Which can be a good thing in some situations, albeit overwhelming and petrifying in others. Public speaking comes to mind. As an introvert, I’m not one to seek center stage but I’m good if I can talk about stuff that’s not me. Whatever insecurities I have about that, I beat with preparation. Probably too much of it but as long as it makes me feel confident that nobody will regret putting me up on that stage, I’ll consider it a win.
Same for writing articles. You can bet I’ll double-check every claim and won’t waste any print space on filler lines. I’m more lenient in my own blog, naturally, that’s why it’s a blog. But recently I started digesting some of the articles into an ebook - and I’m back to double-checking and compressing.
The thing is, outside of a very small circle, I’m not so well-known. It’s very unlikely that I’ll win over readers or audiences or publishers, for that matter, by merit of my name. So I’m very self-conscious about making the thing itself worthwhile. And very perplexed and cautious whenever I get away with my stuff.
