When Jason Alba of JibberJobber.com hurt his calf, it made him think over how similarly he'd taken care of himself and his career (and not in a good way).
This is an excellent example of extending life lessons, and it's one relevant to one's career – and of course, one's life. I often preach leading an integrated life, and this is a good example.
We're going to encounter many lessons in our life – but it's all too easy to think they only teach us something about a specialized area of our life. Instead, I find it useful to try and apply any lessons we learn to the whole of my life, and see what we can learn.
