It took me 5 years to do it properly. I read tomes on the subject (the 4-hour work week holds a special place on my bookshelf). There is tons of advice I could give, but to put it bluntly, this advice is useless if your chosen path doesn’t involve your passion.
Because for me escaping the 9-5 isn’t just about putting your business online (and if that’s what you want I can suggest several mentors), it’s an idealogy to live life to the full, doing what only you can do best and doing only what makes you happy. If this is true for you too, then welcome on board. This sections contains a lot of lessons learnt from the mundane to the sublime.
