Nice article. The best advice ever given to me by a Prince’s Trust mentor, (a senior B.T. Director), 10 yrs ago was to work hard during work hrs, get your job done and go home on time guilt free and switch off. The people he often worried about more were the people hanging around late who obviously couldn’t get their work done in normal hours. I’ve found that to be true wherever I’ve worked. I’m both self-employed and part of a startup and find a healthy balance makes you more focused when it is time to fire up the laptop.
