"It does not matter how slow you go so long as you do not stop".

I affirmatively agree with the quote stated above.
Rushing things to be done quickly may be good at the
surface (your higher-ups might think you have such an
efficient working skill) but it will always bring no
beneficial effects aftermaths. Take me as an example; I
always like to get things done fast because I can't
stand doing routine things, so what has turned up is
just a mess and I always have to do the same thing twice
or more times which I beckon as not efficient.
Although you may not be able to catch up the speed that
others can go, but EFFICIENCY is more important on top
of speed. As I mentioned above, although you can speed
up doing things and finish it within the deadlines that
doesn't hint anything that you can do it RIGHT.
Having said that, it will be better if you possess both
SPEED and EFFICIENCY which can be trained and practiced
as time goes by.
