Is this how its meant to be?

Sometimes when we sit and wonder..when and how did we fall into some problem..we usually find us asking this question to ourselves 'is this how its meant to be?'. Do we usually do the things the way we have planned or we have our thoughts over analyzing the possible future outcomes and ruin it all for the present? and later by falling into the trap of over thinking we regret and swear not to over think again? But are we successful? At night when we are retiring to bed why do we feel that "how i wish i had given my extra bit to save this trouble'..do you see that you are blaming yourself for something which you wanted but do not have due to someone else's flaws? why does that happen? Is that how its meant to be? Why can we just follow the quotes of "living live to its fullest" or "never having regrets" etc...it is always easier said than done...and in a few days i see myself giving this advice to an upset friend too...even though inside i know none of my words would affect her..as the same words never affected me...but still that is how we live..and maybe that is how its meant to be...
