What if...?

Its funny, I used to sit there wondering...what if? You know, what if I didn't try what if I didn't get that chance, to just know. To experiance what I was longing for, to just jump in and not care but really throw myself out there like take it or leave it.
I lived a whole lifetime with that mentality, the mentality of "f it" but yet always wondering what if? You know, you can't go back and redo the past but you could change your future.
But what does the future hold? Will there always be uncertainty? Will I make a decision I live to regret? I did that before and regret it everyday but learned an awesome lesson for it. They say "the grass is always greener on the other side", I wonder is it because your used to the grass on your side? Cuz when we get to that "other side", I'm sure the grass will be greener on the other side again, the side you are not on.
There is that movie "The Butterfly Effect" where he gets to see how his life would have played out had he chosen to change one single event. I wondered that too. But the thing is...now I know. I really don't have to wonder about that one person, or one thing or whatever. I know now, and now the grass isn't so green. It has weeds in it and those little flowers that look so pretty...have bees on em, and the grass is more of a yellow color. The thing is, all the grass is like that now. So maybe its not greener grass Im looking for, maybe its a different field all together. Maybe I'm allergic to grass.
