I'm a blooming, bouncing beginning
A name not bound to only one meaning
Somewhere I fall prey to time and gravity
The other alternating the ups and downs for eternity
The last needs no ladder to rise above its original captivity
To poets a life cycle is brought
To pilots a lifeline/lifesaver they resort
To needy throats surely a life-support
Rumpelstiltskin I am not
But a bouquet for you who got me sort
