On some level, problems are immutable:
A broken faucet is a broken faucet.
A challenging professional relationship is a challenging professional relationship.
An underperforming quarter is an underperforming quarter.
On the other hand, you have a great deal of freedom when it comes to the thoughts you use to frame a problem — both in terms of how you see it presently and how you choose to move forward in light of it.
So what’s it gonna be?
A headache or a unique learning opportunity?
A period of angst or a period of growth (sometimes it can be a little bit of both!)?
In case it’s not clear yet: you get to choose.
