I happen to believe it to be false. You can claim this is an axiom as well, but doing so is pragmatically as useless as the following:
Axiom: I want to be rich.
Axiom: I cannot be rich unless I quit this mediocre job.
Conclusion: I should quit this mediocre job.
...sure, it might be true that you can become rich by quitting that job, but it also might be quite false--it could actually hurt.
It might, but it's nevertheless the most logical step if the given individual wants to attain his goal of being rich.
I want to be fit, as quickly as possible.
The best way to get fit is by going outside to jog occasionally.
Conclusion: I should occasionally go outside and jog.
Sure, it could actually hurt (ie, you could get run over on your jog), but that doesn't make the conclusion any less logical.
If the person's goal is to get rich, and the only way of doing so is (at least in part) by quitting his job, then he should quit his job. As far as your axiom's are concerned, he doesn't have to quit it now, he could plan out his methodology of getting rich, and then quit as part of putting his methods into action, but if he wants to get rich, then he, sooner or later, *will* have to quit that job...
Being the most logical action and being an axiom are different things, though. The point is you can't assume something to be true to suit your goal whilst acknowledging the possibility of it being false, and still call it an axiom.
If the person's goal is to get rich, they very well might believe the only way to achieve that is quitting their mediocre job, either now or in some near or distant future based upon a plan that's logically sound. If they worked harder at their mediocre job rather than daydreaming about being rich in some other fashion they might be promoted to a better position anyway. The proposition that you HAVE to quit your job to become rich isn't true, and you are aware it isn't true. It's a possibility, and it may be the most logical action.
Choosing one possibility over another is quite alright and can be logical, but you can't erase one possibility to make another the ONLY possibility and still call it logic.
