Jack of Diamonds.

Sometimes you put your all into something and it just doesn't seem to connect for you. It's like walking on a travellator moving in the opposite direction, you walk and walk as fast as you can but it's just not fast enough. Sure you're not moving backwards, and you're pretty ahead of some people, but at least they're moving in some direction while you're just there, stationary at that same point on that travellator. You're exhausted, you're frustrated, you want a break. But the minute you stop to take a rest, you know you'll fall back and honestly, that's not something you can afford right now. So you hang in there and then you start questioning yourself. Why are you even on that travellator to start? But try as you might, you find no answer.

A jack of all traits is a master of none.
In the realm of playing cards, I'd prolly be the Jack of Diamonds, easily inferior to the rest of the Jacks; too large to join the numbers but too small to be part of the Royals.

But they say diamonds are precious. Let's hope they're right, because I sure don't feel that way right now. Someone please oh please show me how to refine this diamond in the rough, if that's truly what it is. Please.
