You don’t even have to do that.
Essentially all our knowledge is in books and online.
If you want to know about something, you can teach yourself.
When your business gets big enough, you can hire others with the needed talents where you direct and delegate the overall work.
The problem is, that like it or not, we have created a society where one must pay admission to play the game at a certain level.
And the price of that admission is a college degree. More often than not any degree will do, you just have the sheepskin...
There are far too many jobs that just require a degree, any degree... even though 99% of what you need to know to do the job will be taught to you after you are hired.
But its just that way, you want that job you’ll pay for admission, by getting a degree.
Personally I think college is completely unnecessary for 75% of those who are going.
That says it all!
