Rancours, bubbles to the surface when you least expect it.
The feeling that you aren't appreciated, that you could do so much better, that you are not achieving everything you are capable of. That you made wrong choices, you heedlessly stepped on a green path and you're not sure if you're ever going to reach the sunlight as you trudge beneath the monotonous canopy of expectations and unfulfilled dreams and the susurrus of time as it flows by - if you listen closely you can hear the grains falling in the hourglass that holds your earthly hours.
You tell assuring stories to yourself about individuality and different definitions of success until you can't be sure where reality ends and your dreams begin. Or were they intertwined from the very beginning?
But there is light, there is meaning, there is hope: lift your eyes from the crunching dead leaves you step on, and with filmy eyes envision the road to come. While your feet have strength, walk straight, walk upright, walk forward.
