I love to studying alone, that's how I learnt everything I know about english.
I believe that there is not such thing like a "natural self-taught". We all can be self-taught and the education we receive should just prepare us for that.
The advantages are many:
- you control your schedule
- you study whatever you feel is most important for you, without being restricted by rigid "planned books" made by someone else.
- you exercise your independence, your curiosity and your problem solving skills.
Of course, for me, studying alone doesn't mean to be closed in your room and apart from social contact. I think studying alone provides even more chances for us to seek for another "self-taught" learners willing to improve in whatever field you are interested.
The thing is that some people who say that "only can learn with a teacher telling me everything" put thenselves in such passive learning condition that makes learning tedious, harder and inefficient.
There are some disadvantages for the "lone learner" just in relation to a learner who, besides having a good teacher, is a self taught hinself. In other words, having a teacher is going to potentialize the results for the self taught.
I think this is it!
