So dear, why do you feel inferior? Everyone is moving forward, just taking different paths. Each road has its own pains and gains, which the other road does not have. You have gained experience by choosing this road. This is a precious thing that their students can't understand. You don't need to feel inferior.
You should bravely raise your head and tell them loudly that I am working now, where I am, what you have seen and heard, and your life, all of which they don't have. It's an experience you should be proud of.
Also, you need to make it clear whether you envy their free college life or the knowledge they have learned. If it is the former, it is completely unnecessary. Now there are more ignorant teenagers fooling around in universities, wasting their parents' hard-earned money and national resources. If it is the latter, it is even more unnecessary. Now, there are many self-taught exams and adult college entrance examinations. Choose what suits you and work hard. You don't have to be worse than anyone else, but you are more than others. Tell them loudly that I am working. What a big gap.
