Really this is a lifestyle question.
You can make $50,000 / year as a marine biologist, perhaps live near the ocean in a small city, work for 43 years because you love it and retire with a paid for house and some money socked away. Will your family resent being a bit less well off so that you enjoy your life while you work?
You can make $75,000 / year as a <insert here>, live in an expensive city far from the ocean, work for 38 years and retire early because you can't stand working another minute, and have a bigger house and more money socked away. Will you resent your family for choosing a career you didn't care for?
Who knows? That's a choice. You get one life and that's it. In 38 or 43 years, you will have been given a pile of cash for doing something you didn't like. If the pile of cash is really important, the career choice is meaningless. If the career choice is important, then the pile of cash is meaningless.
I don't want to make light of this, but one can downgrade his/her hopes or downgrade his/her life style. Both are possible.
