The value of education
Education is when the knowledge gained in childhood and gained when there were good teachers in the family, school, institute. And when one pulls up to them again, if there is not enough knowledge in any area. Generally education is when you learn more, get more practical skills, in the end - in what area you understand, whether you have the skills that are exactly needed in a new field of activity. Example: if you don't know anything about space, you can't go into space.
Even if you've been specially taught it won't come in handy - what are you going to do in space?
But if you start studying it you will quickly develop in any sphere of activity which is connected with space. Education. A profession is always a plus to experience, a plus to knowledge. Nobody comes out of school profane with a level of theoretical knowledge and practice.
If a person knows what "optimization" is, that's already a plus. If he knows how to write it, that's a plus to the profile. Pro to experience and knowledge never hurts. Education has a price. The price depends on the chosen field, as well as the qualifications of the teacher. The possibility of re-education, a passing grade for admission to any university, free tuition in higher education are permanent pluses.
