Life...as it comes !?!?

Tell me something...

Sounds pretty cool but does the line "Take life as it comes..." really hold any water ? Its easy to sound ideallistic and say that "I have no rules" ..."I will go with the flow"..."I am open to experiences". But is it possible? How can you totally disregard the boundaries that are very much there? Does it mean...you should not stop yourself from falling for someone who in all common sense can never be yours? Does it mean...its okay to let go of your dreams if reaching for them isn't in agreement with the "plans life has made for you"? Does it mean...compromising for the stuff that happens to you rather than taking the world on for what you "really want"? I would sure love it...but is it possible? And please, don't quote me a line from Ayn Rand's "Fountainhead" !!!

I don't know. Frankly. I have no clue.
