Wherewithal comes from where and withal (meaning “with”), and it has been used as a conjunction meaning “with or by means of which” and as a pronoun meaning “that with or by which.” These days, however, it is almost always used as a noun referring to the means or resources a person has at one’s disposal—especially financial resources.
The most important “means or resources” a person can possess is knowledge, a desire to excel, and good work ethic. With those two core ingredients I believe a person can achieve just about anything.
Wherewithhaul, is of course, a play on the spelling of wherewithal, with an obvious nod to U-Haul, my current employer.
