Life is like a liquid, like water or milk; it spills or I should say it is always spilling as life is a flow a continuum. No matter how careful you are in handling, it cannot be made water tight.
And it is wise to allow it to spill as there is no other option. If allowed to spill, whatever amount has to spill will spill and then it will not, it will stabilize.
There is trouble if one tries to contain the spilling. So, if life has to go on smoothly, whatever spills should be allowed to spill.
