A formal education is great. but it is not the only way to learn. So long as you can read and digest information, you can learn. So read what you are interested in and let those topics organically lead you from one subject to another. You will learn naturally without pressure to keep up with a curriculum. This approach is known as Interest Based Learning. Many home schoolers are familiar with this style of learning but it is atypical for all other styles of formal education. I wasn’t home schooled, but can see how this environment is great for picking up and diving deeper into new subjects.
