If you asked this question 5-10 years ago, I will answer yes, higher education is very imporant for success in life.
Now, more important than formal education is experience, ability, recognition of real opportunities etc.
For example, even with only primary school and basic knowledge in English, and Internet connection, anybody could buy some bitcoin 10 years ago and become very rich today

I don't say that higher education is not important but is less important than before.
Thats a very good point. Some also say, the most successful people didnt even achieve so much with regards to their education. I dont believe in school systems either, numbers do not measure a persons intellect and knowledge. We are all different and we excel in our own unique ways if only the society can see this, sadly no. Educational attainment is important in some countries, it is a basis if youre qualified for a job or any responsibility. I think its good but the common problem is discrimination of the attainment plus the attended school. Some employers offer higher salary to those who went to prestigious schools, rather than give them to employees whom are scholars at public/unknown schools. Anyway, just remember, whatever you achieved, be proud of them. Your success is your success stop comparing yourself to others.
there is an expression: education will help you survive,self-education will lead you to success. there are many examples in which people with two higher educations cannot find work. maybe they do not want to look for,maybe they do not want to work for the pennies that they are offered. everyone has their own reasons,but it's a fact. there are also many examples in which people with only school education have made significant progress in life. the question is what goals and objectives each person sets for himself,how consistent and purposeful he is in achieving his goals.
As the protagonist of the novel Mario Puzo said: "It does not matter which way you choose in life. It is important that this path is the only right one for you.
