Affiliate Marketing Secrets

I am 29 years old and despite being employed and very much employable, I have never quite found my niche, never quite found satisfaction in any of the bottom line obsessed jobs i’ve had since leaving school.
I very nearly joined the army at 16 but didnt quite follow through, ive always really really fancied it but despite knowing the age limit is 34 i felt like maybe i was too old. I have no problems being told what to do, I am fit, or at least “always playing football and 2 circuit training classed a week” fit not “army fit” and liek i say i have a real desire for something out of teh ordinary.
I have a few gcse’s in eng, maths, I.T. etc so would appreciate any advice of what to join if indeed you would reccommend i did. I read good things about the subsidised living side of the army and see that a starting salary of 17.500 which is only slightly less than i get now…..
any advice or tips greatly appreciated.
