YOu can make a lot of study depending on what you like to discover or to learn something.

I quite agree with @thunderbitz2717 and I am living proof that this approach actually works quite well ; )
I have acquired several skills completely online. It may not be the traditional approach, so depending on one's domain of expertise, gaining recognition may be slightly less easy. However, nowadays there is a variety of online courses available that issue official certificates, and I think this kind of 'personalized education' will be gaining even more momentum in future! So the answer is: Yes, absolutely!
