When asked “What’s your dream job?” do you automatically say to be a manager/boss of a multi-million dollar company? If yes, good for you; you have a clear goal, right? Not for people who have already been burned out by the office politics, stressing commute to work and all corporate conundrums, though.
Some people prefer staying at home due to lack of job opportunities (or are being picky at it), or would want to oversee the growth of their children or just about any reason a work-at-home enthusiast can add.
Working on home-based jobs virtually has no definite date of conception. It can be found to have started among the earliest settlers from where office-type work then had not been common.
