@litewave,
In that case, I think you're tailoring your terms to your thesis.
You're using the word "reason(s)" without any dimension whatsoever. The reason a apple falls from a tree is the combination of the stem weakening and the mass of the apple being drawn to the greater mass of the earth. The reason a person chooses a career is a combination of factors too. The sum of those factors does not come out to a calculated answer. A person may choose their career because they are good at something, the money it makes, or even just because it is easiest. Some choices will obviously conflict and we get to decide what we value most.
You seem to be blurring reasoning and causation.
