Life lesson: don't waste 7 years of your life and and personal growth on some weird fringe language, you will not get them back. It can pay off to make a serious commitment to a non-mainstream technology, but basically only if it allows you to do some very concrete things that give you a big competitive advantage and that you could not reasonably achieve otherwise. Or if you are both unusually good at predicting the next hot thing, and the timescales are short enough. Racket is not a good bet in either regard (even if it's a great language to learn certain concepts). All the lost productivity the poster is bemoaning could have gone into mastering hard and useful skills instead and these things compound.
