I've yet to make a mistake, but I will report back when I do. As an aside, you can always use personal tags too. for example, if you were to tag this vaguequestions@ it would show up vaguequestions.nowaypablo and people could follow it. This tag would be unique to you and nobody else could post under it. Right now, anyone can post with the tag #vaguequestionsbypablo Most, not all of the mistakes I've made turn out for the best. For example, I dropped out of college and that was certainly a mistake but I ended up going back and who knows what would be different if I hadn't dropped out. Could be that I ended up in some bull-shit job out of college that I got stuck in. Instead, I pursued a number of interesting career paths that led me to where I am and I'm very happy with that. There are some HUGE mistakes I have made that I'll keep to myself but most of the time things have a way of working out.
