If you don't study don't expect to be more than a junker!! Said that, even having studies do not grant a good job, but without it, it's even more difficult. Aren't you investing a lot of time mining and hauling in game to have that goodie (Battleship, transport, base) ... the same can be applyed in real life, but in a harder way!!!! If you don't invest in studying now, you will remember that in the future, that is for sure.
