If you're talking about worth in terms of cash, I would run don't walk away from the PhD.

If you're talking about worth in terms of cherished personal values, I would try to figure out if I want to be a scientist or an engineer. If it is a vocation.

Through my master's program, this was on my mind while doing my thesis. I ended up deciding against choosing a narrow specialty and becoming a miner, so I headed to industry to become a maker.

Neither choice is the less noble.
