the biggest decisions in life

what r the biggest decisions one will have to make in life? r they the ones abt choosing ur life partner, college, job or place u stay? i dont know...maybe the biggest ones are those that if u realize u've made the wrong choice, u tend to regret it altogether...and can never seem to forget them....maybe its one of the thngs listed above.. a job u took...when ur at the peak of ur career u turn down a great offer? but why? did u hope for somethng better than us....maybe greed is a factor...we strive n thrive for more...u may not b materialistic...but u stil want more than u have (currently) right? take time to think abt this...think long n hard ;)
