Since I have been learning maths i can say that many people has learned with me too.  I had read some books or practiced lonely.  In past I didn't like maths because I couldn't understand them, anyway someone once said, never surrender before difficulties, 

Opportunties are whereever you have thought as possible, our brain set what is possible, in past, present or future time.  remember those people as Julio Verne whom dreamed about trisp to the moon, since 1865, that was one century ago.

Many people has made mistakes during all its life, but those who adjusted its way are those ones whom got the goal, some other continue in the same way, so it is possble they have not considered something to get out that hole

Espero sea lo que buscas
