Am I wright. right?

Day by day it becomes harder for me. I don't know what will be the final result but I am trying to give all my positive effort. Removing all negative thinking from my mind I become more and more practical. I think it is the best time for keeping silent because I shall get some time to think what I should do and what I shouldn't .
