I share the same sentiments. Just substitute engineering above to accounting (specifically taxation). I've had thoughts about possibly going back to school or switching careers. As many of Buffett's shareholder letters have summed up, it's always best to work in something you love. The fact that I don't have a passion in my current field makes me approach it, like, well, a job. My feeling is that I can always use accounting as a fall back. However, it does seem that once you're labelled an accountant, it's difficult to changed that perception. The kicker to me is that I always viewed finance and accounting as working hand in hand, one doesn't really operate without the other.
I do enjoy investing, specifically value investing since it resonates with me quite well. For now, I invest on a personal level as well. I appreciate what you've done with your website and feel like it's been very useful/helpful. To your credit, there are successful practitioners that make terrible teachers. I think you'd do a fine job as both.
