how does one turn a small problem into a big problem?

easy.
just let emotion get the better of you.
vent your rage.
say what you secretly think.
do what you know you ought not to -
but that you feel so tempted to just do anyhow.

really.
please hold back the applause.
there's no great art to any of this.

start giving way to your negative mood
and
everything will automatically go from bad to worse.

now what perplexes me is if the reverse can be true..
can one really turn a big problem into a small one just by rising above it?
