When I started in the industry I worked from the moment I woke up until I couldn't take it anymore. That's the nature of startups. I had a small UK based hosting company back then. A few years on I am now able to be more relaxed, with staff doing much of the leg work. But the funny thing is- I actually miss those early days. Strange!
I work long hours as well.Because we have to give support to our clients anytime.Our business requires fast response to our clients.
