I don't think that the guy's question was all that bad. There's nothing wrong with having a bit of ambition in your life, and with everyone on this forum saying how bad things are, surely that's more of an incentive to supplement your income by a small side business. As he rightly says, many guys do it, and all he is asking at the moment is some details from people. Are you suggesting that with 5 days off after a long-haul that he spend everyday studying? There's nothing wrong with asking about details from someone who may be able to provide them.
