What books have you read? There's no one "best way" of self-learning, some people learn best by doing, some by reading and some by listening. You need to find out what is your "best way" of learning regardless of the subject for starters. So you may have to skip some chess and read up on learning techniques instead.
In the meantime start doing the Tactics Trainer 2-4x a wk and inbetween start doing whatever else is available here, chess mentor or whatever.
GOOD LUCK!
What is the best way of self-learning?
I started playing chess 3 years ago...Then my rating was about 1100 in blitz games.. I studied from different simulators, i have read different books...today my rating is about 1450-1500..it has been that number fo some time..but thats it.. i feel like there is no more progress..and i feel like i dont have so much enthusiasm like i had before.. maybe someone found himself in a similar situation..?
