Am I strong enough?

I'm afraid that I'm not strong enough
coz when you are not, you commit mistakes.
and the mistakes scare me more
as they effect not just me
but everyone around me.
they could have been easily avoided
if I had been fixed on
my motives and principles,
but it's harder to follow your principles
when you are breaking,
breaking facing the harsh realities .
somehow those realities evolve everytime
and they break me even when I thought
I was doing okay, I was standing strong.
maybe there's no strong enough
to make you strong enough,
as I was strong until I was not
and I am strong until I'm.....
