Never assume you know,  there is always something different or new to learn.
Never assume people know,
most of the population can not read your thoughts :-),
so be open and express what do you want and don't,
what do you think, ask for things, favors,
everybody is busy with their own lives
but that does not mean they do not wanna listen to you or help you.
Never assume what someone told you is the truth, why?
are they Gods? there is not a different perspective or approach to affirmations?
As a Political Science analyst, I have learned and been taught that
you always have to use the dialectic to be able to have the peripheral vision
and a broad understanding of a fact.
Never assume something has been already done,
because no one except you to know what has to be done,
and even if it has been done, your uniqueness makes it special.
Assumptions will lead you to mistakes and to a flat realm,
where not even dreams are allowed to happen,
do not assume, act, react, move, express, make it happen.
