This kind of experience of yours is a good example of why education shouldn't be the primary aim if it's not required for the part which you choose in life.
I have seen a lot of graduates out there without a job, the response they get from the society out there is very terrible but the problem doesn't end there, if they stay without a well paid job for a long time it will lead to depression. And it was almost the same situation with you, but the difference is that you decided not to give an ear to such response.
I don't care about their sarcasm, I consider it to be the wind. They contribute absolutely nothing to my life, so why should I care what they say. It would be better if I continued to focus on the plan I had made beforehand. Responding to their words will only waste the precious time we have, responding to their words is the same as solving unnecessary problems. Because the best way to silence their mouths is to prove the success we have achieved through the path we have chosen.
It's not very uncommon to hear about that kind of situation where someone who's an undergraduate but still able to be successful in life. The thing is people such as those are the ones who know how to market themselves, either have the skill to communicate better than any of those people who have diplomas or can show more confidence that most of the time needed especially in the corporate world.
It's all about how we apply what we learn in life, not solely the learnings we get in school because not everything we learn at school is useful in life. It is still up to us whether we will use that education to become a better person, or just like above, if you don't finish your education, it's up to how you level up yourself to achieve the needs to start the journey to become successful in life.
Non-academic skills are very important for us to master, because sometimes the reality that occurs in the field is very different from what we learn during college. Although all the knowledge we gain at school is not always practical for our real life, it is important that we put that education into use and utilize it in our day-to-day lives. In this sense, the decision of whether to use education as a means of self-development, or even if we haven't completed any formal education, one can still improve oneself and succeed in achieving his/her goals, lies entirely with us. The point here is to be eager enough and have the diligence to keep learning and developing as a person.
