Your own home is often seen as the ideal working place. Let me tell you one thing: it certainly is the most pleasant place to work in, but you need to be very vigilant about working hours and time off. For a long time I have now been working on a huge project, private for a company I work with. The project is now finished and delivered, all I have to do is deal with the unavoidable typos and bugs.
What does that have to do with photography? Well, being “on call” for fixing bugs and other annoyances results in no real time off. Lunch breaks become working hours as colleagues will more often than not call you during that time as not to interfere with their usual activities. As a result, your lunch break becomes a time of higher stress than the rest of the day. After a while you feel your energy dripping away, never to be recovered.
