Having a college degree only adds value when applying for jobs or makes you look more educated in society. While it's certainly worthwhile in some circumstances, it's not the determining factor for success.
Success is a combination of many factors such as knowledge, experience, skills and discipline, vision and goals or network of relationships...So when it comes to success, we need to combine the elements flexibly. All are equally important, we cannot succeed if we only focus on 1 or 2 factors and consider them as decisive factors.
College degree is not a deciding factor, but with education and qualifications, you will have an advantage in accumulating experience, better thinking ability and building relationships more easily than when you do not have education and degree.
So, it can be said that a degree is not a decisive factor for success, but it will help us a lot if we know how to take advantage of it.
