Yer feelin's is like ras'berry vinegar: if you're skeered to use 'em an' keep on savin' 'em, first thing you know they've done 'vaporated!
Livin' is like pourin' water out of a tumbler into a dang Coca-Cola bottle. If'n you skeered you can't do it, you cain't. If'n you say to yourself, "By dang, I can do it!" then, by dang, you won't slosh a drop.
