There are, simply, some problems we encounter that we cannot overcome.  Training, fortitude, and refusal to surrender do not mean that events or a greater force cannot overwhelm one.

What is the answer?  My answer, perhaps not yours or yours, is to live one day at a time, sometimes one hour at a time and, quite occasionally, one minute at a time.

Remember your mistakes.  Know your weaknesses.  Be very cautious of those who also know your weaknesses and will repeatedly exploit them to destroy you.

There are many out there like that.

I have met them.

They are legion.

So are we.
