Is it better to get an education or the experience that comes with a promotion?
Education pays off down the road. Take the opportunity to get an education over the chance for a promotion.
Sometimes you have to make decisions that will pay off later. Passing up the temporary rewards of promotion in favor of getting an education is one of those times.
A promotion pays off now, with more money and responsibility. But you can get that and more if you get an education.
Promoting too fast can even take away the opportunity to get experience, exposure, and education to help you later in your career.
Do the hard things now so you can have a better life down the road.
