What do we do when things get hard and we want to quit?
We deny it.
Most of the time, anyway. Denial comes in many forms.
We might try to fake it, pretend it's not hard, and force our way through. We might just say, "Piano sucks," and move on with our lives. We might say, "Working out just isn't my thing," and settle for average.
All paths lead to quitting.
There's an alternative, though. Radical honesty. Admitting to oneself, "This is hard. I'm struggling."
We also call this self-awareness. Or even "labelling your emotions."
Sound nauseatingly hokey? Don't knock it until you try it...
Admitting that something is hard opens up another path. A path to figure out how to grow. How to address the difficulty. How to become stronger.
There's no shortage of opportunities to practice being honest with yourself. Give it a try and see what happens. If it doesn't go well, you can always go back to whatever you were doing before.
