If the desire to kill and the opportunity to kill always came together, who would escape hanging? Framed in a more positive light, this tells us also that if we wish to accomplish a particular thing then we need to increase our level of desire for that thing and to create or seek out the opportunities and right environment for it to happen without fail.
Mark TwainI have learned that there lies dormant in the souls of all men a penchant for some particular musical instrument an an unsuspected yearning to play on it, which are bound to wake up an demand attention someday. Therefore you who rail at such that disturb your slumbers with unsuccessful and demoralizing attempts to subjugate a guitar, beware! For sooner or later your own time will come.
Mark Twain
