If you remember that you have forgotten things, then it is not
that bad.
Reach the bus stop then realise you did not bring our ez Link card,
is mundane, nothing serious.
Check your mind, is it cluttered with endless thoughts.
Is your mind on run-a-way mode, thinking of arguments, plans,
girls/boys, exams, money, anything, non-stop.
If you leave your home, with your mind heavily thinking of a
project, or something else, you are most likely to forget
something. Simple things like closing the windows, turning off the
fan, bringing a book, will be overlooked.
Learn to still your mind. Just be aware of where you are and your
surroundings. Not think more than what your eyes sees or ears hear.
Once you experience this "awareness", you are also sort of
alert.
Think when you have to, but control and direct you thoughts to the
task you are doing, or intend to do.
But when your mother stand infront of you, and you don't know who
she is then you better go see a doctor. Quick.
Remember that.
