Scientifically, there is a reason why scratching an itch feels so good.  Doing so releases serotonin, which is a neurotransmitter that plays a part in boosting your mood.

Now take that idea one step forward.

If, metaphorically, your itch was a very real problem that you were trying to solve, and you could scratch away at it to solve it, wouldn’t that make you feel good, even better? 

“Problems are meant to be solved, but unfortunately, a lot of people choose to complain, worry, and cry about them.”
