If you put some fleas in a jar and close the lid, the fleas will begin
to jump, of course with the lid on they will only hit their tiny heads
and never be able to escape. After about 20 minutes they learn
that they are trapped and they change the height of their jumps
so that they will stop hitting their heads.
Give them a little bit longer and they will grow accustomed that
they will never escape and once this happens you can safely
remove the lid and the fleas will continue jumping at the same
medium height, eternally trapped in the jar.
You see they firmly believe that they will never be able to escape
and that's why they stop trying, of course after spending 20 minutes
jumping straight up hitting your head, with no way of escaping, who
wouldn't... The problem is that they get so used to the idea of being
trapped that they never even bother to lift their heads again to see
if the lid has come off...
Having a mentor or guide is a great way to help you keep lifting
your head to see if there is an opening in the jar, you never know
my friend, because just like in the case of the fleas, anything could
happen in 20 minutes.
Never doubt yourself and what you can achieve, put your mind to
it, keep pushing and I promise you that an opening will come.
