You probably don't need anyone to tell you that the end of this legendary lyric is "but if you try sometimes you just might find you'll get what you need." As a kid, I hated this line and viewed the song overall as a rather depressing one. As children in the land of the "American Dream" we are raised to believe that if we work hard enough and put our minds to it, we can achieve anything we want and the idea that this might not be the case seems preposterous and downright offensive. Why can't you get what you want? Plenty of people do and you intend to be one of them.
Yet as we grow up we come to realize that this is not always the case and things will not always (or usually) go the way we plan (I'm fairly certain that's really the main theme in How I Met Your Mother). No one (despite what you parents might think) plans to move home to their childhood bedroom after college. No one plans to get turned down for their dream job. No one moves to New York to get denied by countless record labels. No one plans to graduate from college with nearly six figures in student loans and no job prospects. Yet sadly, these are the realities many young people today face. We were supposed to be counting our GRAMMY Nominations by now, right?
The Stones weren't necessarily singing about desperation and defeat though. There is, after all, an unmistakable note of hope and optimism in that famous melody. Sometimes life knows you better than you do.
The truth is sometimes the best things are those we could never have planned for and even those we never knew we wanted. When you miss out on a great opportunity, perhaps it is because a better one is waiting for you or because there is something you're meant to learn from it. Sometimes what you want isn't actually what's best for you and you have to have a bit of faith that life will work out if you keep working hard and continuing to learn and do better. Try to see the value in every opportunity, because it may wind up being worth far more than you could ever have imagined.
