Trying to pick my mos?

going to the marines. my original plan was to go 7051, fire crash crew. but im being told now that job is being contracted out to civilians or will be soon. which sucks. basically i dont want to be a mechanic or clerk or in communications. the things i like dont really help me decide. i like philosophy, world religions, most scientific fields, ect. the only thing that i can think of is infantry but people keep telling me that it sucks. also thinking of artillery. one of my friends did radar artillery and he said he liked it. any of your own personal experiences or preferences would be helpful. i just need to make up my mind and quick.
