uncertain

one thing i've learned during this practicum is that you can never be so sure about the future
you can always planned your lessons beforehand
you went all out planning the best lessons, filled with creative activities yada yada
but you can never be so sure that the lesson will be carried out successfully
because you can't predict the kids behaviour
they might be total angles today
but tomorrow they could changed into some unmanageable lil monsters instead

you can never be so sure that you can do exactly like you've planned
there are many factors that affect the students' behaviour such as the weather, time, their workload, what happend in the previous class etc .
something that you have no control over.

the same concept of uncertainty applies to life in general:

-you planned to go out for a jog and suddenly the rain pours in
-you like the blouse and planning to buy it but they don't have it in your size
-you fell in love and planning to have a future together but your family disapproved of that person

there are always unpredictable circumstances that could ruined your plans.
but that doesnt mean that we should not be making any plans at all
we could always plan for the best
but be sure to prepare for the worst.
