so sorry I wasn't clearer. yeah i'll need 5 specialties...but is it worth my money to take up these 5 specialties, or shall i just be happy with my rescue, and just dive

looking at the list of specialties, nothing really screams out at me. i'll do enriched air for sure. the rest...kinda iffy. I mean...peak buoyancy? just jump in and dive, and the buoyancy will come in my humble opinion. and wreck diving? I did that for AOW and we just counted kick cycles, and estimated the size of the wreck, and got oriented with it's topography (to be able to find it again.) and if this is the sort of thing i'd be doing, I rather not spend over a hundred bucks to do this.
Sorry for the cynicism but if I invest money, I wanna learn something practical and IMPROVE myself. thanks for all the replies so far folks, appreciate it.
