So good luck mate, and as for the Mrs just show her a few threads where people are boasting on how much money they earn I'm sure she will see more positives then lol.

Yes good luck to you. but don't take it as gospel these so called threads where people say they are earning vast amounts per day. Yes it can be done and yes some people achieve it, but mostly it is when you have been going for a few years and have more confidence in what you are doing you then get the odd day which turns out to be really good.
Someone else said about viewing it as a job and not a doss.....true words, but don't view it as a job,otherwise it will own you!!! view it as a business that you run and control.
Good points on the downside whoever made them, yes there are downsides i'm afraid and I expect like us all you will get some that nobody else has ever experienced, just go with the flow and keep on at it. IT may be hard with the so called finance problems in the world at the moment, but if you think cleverley and keep focused you should be ok.
