Ok just thought I throw in some advice, same age as emttim but no offense mate your attitude reminds me of myself about 4 years ago when I thought I knew everything and had my next 15 years planned out

. I have finished seven years of college last year and have changed my mind about my long term career future about three times in that period. Two years into college is not a lot, who knows what you will want to do in after another few years? When I was 17 I got a job in accounting and thought that was my life career, at 19 I picked my Economics major and thought I'd go with a career in that. At 23 I am now working in IT! Who knows what it will be in another few years (diving instructor??

) These days I have realised that I am more likely to miss out on what I really want to do if I decide to pick one thing and stick with it. My only consistent loves have been marine life + wrecks (hence the diving) and mathematics! Keep your mind open and don't be too proud to change it.
Re your current goal: I have run my own business as well as other work and study for 3 years, my partner also has for about 10 years - from my experience, you really have to know the industry (this applies to all industries, not just diving) you want to get into *very* well before making such concrete plans you have mentioned here. 0-24 dives and little training is not knowing the dive industry well enough to be setting such concrete plans.
Also, on a separate note, this doesn't endear people to you in places like an internet forum as you have no way of backing it up and it just makes you look arrogant (even if it is true!). Again this points to a lack of self-reflection about how you come across to the rest of the world which you will really need to work out before putting any of your big plans into action.
I mean this as constructive criticism and apologies if it comes out harsh! Hard to convey things like these over a forum... My 2c.
