"Difficult circumstances can only make planning difficult; not optional"

Planning can sometimes be very difficult, but never optional

When things are predictable, planning is easy. When things are unpredictable, or circumstances are not conducive to planning, planning might become very difficult, so diffilcut that plans might have to be revised frequently; it might seem that planning is not possible. 

But we need to remind ourselves that planning is never an option, it has to be done no matter what. It can get difficult sometimes, thats it
