Overall, being an adult, can be broken down into 2 component.
Survival, you're given the responsibility to earn at least enough to NOT DIE.
Innovation, if your Earning EXCEEDS the necessary requirement to survive, whatever sum existing beyond such range is SOCIETY'S TRUST in YOU to appropriate through YOUR INTERPRETATION/ WILLFULNESS-TO_ACT.
When your interpretation of necessary action is deemed worthy of exploration and continued innovation, then society will continue to fund your lead of such objectives. (pay you more money)
You can assess your objective (MOST SIMPLY), by asking 2 simple questions.
-Does your objective -SOMEHOW- increase the efficiency of a HUMAN action in the Chain of reproduction (be it communication 'facebook', health 'birthing technique', erotic literature 'mating efficiency', etc
Many many things.. But it must fall in line some where. Even for example, Aerospace, if you asked, hai-Tp.. What the hell does a rocket have to do with human reproduction.
Well, we have limited resources on earth, it is exhaustible, which means we NEED rockets, however later to continue this PREDETERMINED goal of "LIFE" which is very basically CONTINUED reproduction FOREVER..
The entry point into this cycle may have been random/accidental, but by design we are DOOMED to repeat it until all resources are converted to HUMAN mass. <assuming we could> it's very possible we'd not cross the empty barriers of space.. the Iceage has never stopped in SPACE..
Because we have to balance this THRESHOLD choice, with our current LIMITATION of materials.
The SECOND important question, in your quest of humanity, is:
-Is YOUR chosen path sustainable and continuously efficient, under and throughout, YOUR allotted time of management.
