Yep. Try it! Yes I do
how to improve my lazziness? I hate to sit down and read new theory arghhh
Then don't sit :p idk how to overcome laziness but try to take some time to do revision, and revise at the same time the next day. Repeat it for one/two weeks until it become a routine so that you won't feel lazy anymore ^__^
