The more you learn the more you get confused by data and information

 What to do when you learn something but then when it comes to use it you don't know how to use it.  do you do compromise with just dealing with what you have learnt by ignoring what you didn't learn or you look for better teacher or books or sources to learn it until you know you know now how to use what you learnt by acquiring more inputs in the knowledge. I thought i learnt this technique but I am now even more confused. may be i don't wan to compromise or may be its a fear of dealing with unknown result once i apply this new knowledge because still now i have known how the existing things works well but i don't know how the new one will work .  I try this everyday little by little but end up on the same damn conclusion. because people say so but if what people says is so wrong then how come i was able to deal with it till now? am i a super human or i am just used to get hit by bus all the time. for now i am still looking for the right solution because there is no right now may be there is i don't know time to try more..
