Midlife

I think I am having a midlife. It would be called a midlife crisis by some but I don't particularly feel it is a "crisis" - my family and I are happy, we are financially sound and we are in good health. So no worries on that front, just maybe a career change is needed or maybe a change of location. I like my contract work in the City because it pays well but if the money disappears then so do I. I have toyed with the idea of teaching English as a foreign language but I worry about the amount of prep required and the standard of my grammar ain't great. However, I do enjoy my language exchanges with Juan in Madrid so maybe I should investigate further the teaching option. Apart from that, I really don't have a clue. Any ideas?
