Lived longer and i can see the world for how it is like many, it is not meant to discourage you it is to make sure that you REALLY will get somewhere, if you do not get somewhere all of this is in vein and you end up in a shit load of debt, depression, possibly some mental anguish trying to help yourself out of that hole, when you could make it far simpler and just work hard whilst gathering resources by saving.
also economics without maths but what i mentioned before.
