I've worked minimum wage for years to be able to afford rent/car/college so anything above that is financially rewarding
I love maths so Mechanical Engineering is great for me (so far, anyway).
I actually find that engineering seems a relatively popular choice now - loads of jobs there etc. (hope that's the case in 3 years too).
I'm pretty existential and nihilistic so I like to say feckit, we're all going to die anyway so if society is going to burn the world to the ground we might as well enjoy the time we have left, and do what we can ourselves (as insignificant as our input is vs massive corporations) to reverse it.
