My study has been a failure and inefficient and ineffective for 3 years

Now it is time to change. It has been a failure for me to get anything out of my study. However, now I found the way to work efficiently and get the results. I am developing a pragmatic view and hit directly to the goal.

I must elimiate years of failures, and start to aim at success. I will succeed if I really aim at success.
Study will be easier and enjoyable now.
I am so eager to get it.
Hate theories and useless things.
