Priorities Intact lyrics

Here I sit, my life's a model kit
But I burned the instructions and the pieces don't fit
I eat Spaghettio's, turn on the stereo
And keep in mind my best case scenario
Oh, I'm without serious doubt, oh, I'm within my constraints (hey hey hey)
Oh, I'm without serious doubt
And it just clicked, the things that make me tick
Get thrown against the wall and I keep what sticks
I wish with all my might that I had a cause to fight
But I can't argue with myself on this lonesome night
Oh, I'm without serious doubt, oh, I'm within my constraints (hey hey hey)
Oh, I'm without serious doubt
I can't complain, lost less than gained
Strive for progression
My futile needs are all I feed
It gives me indigestion (let's go)
