awareness is part of the answer

Sometimes I observe people blaming an activity or an environment or something for a personal failing.

A thing I'm learning to do is be more aware of the choices I'm making in each moment:

choices of focus

choices of response; rather than reaction

I think what's going on around you really doesn't matter...
so long as you are truly aware of what's going on; especially inside your self.

I'm learning to use the question:
"Is this worth my time?"
"Is this action congruent with my desired outcome/s?"

So things like getting caught-up in vain discussion>argument...
tend to happen less.
