Thing to do in the game

This is the big question, what should you do to keep you occupied with the game? The answer I would like to give is, anything you want.

You can buy a truck and become a trader or a hauler.
You can do some mission running.
You can buy an off-roader and go do some exploring.
You could go to the wrong side of the law, taking shelter in raider bases, attacking convoys, looting what you can.
You could be the opposite of above, a bounty hunter, attacking raiders and raider bases, protecting convoys and such.
You could put all your effort into making yourself a big name in the manufacturing business.

I'm trying to think of more things you could do all the time, but the key point is that you are not forced to do anything, but instead, encouraged to do what you want.
