Present three examples that illustrate how all decisions involve trade-offs

It is probably safe to say that most if not all decisions involve trade-offs. For example a person may be offered a job that pays well but requires 7 days per week for a month and while this is good for a younger person with no other commitments it may not work for an older person with his own family commitments and other projects. Another decision could be that for support, a husband decides to not take on major time consuming projects while his wife is doing intensive studying to become certified in a field of her choosing  so that he can support her. Another example is that when one cannot drive one's son with a disability to a beach to swim because it is too far and uses too much car gas, the money saved on gas some of it could be spent on his groceries.
