What is a personal calling? It is God's blessing, it is the path that God chose for you here on Earth. Whenever we do something that fills us with enthusiasm, we are following our legend. However, we don't all have the courage to confront our own dream.
Haven't you learned anything, not even with the approach of death? Stop thinking all the time that you're in the way, that you're bothering the person next to you. If people don't like it, they can complain. And if they don't have the courage to complain, that's their problem.
When we're interested in something, everything around us appears to refer to it (the mystics call these phenomena 'signs', the sceptics 'coincidence', and psychologists 'concentrated focus', although I've yet to find out what term historians would use).
