You could improve this piece by taking more risks. As it is now, "Love is..." is comprised of several highly familiar phrases strung together. Yes, love is powerful, and yes, people fight for love their entire lives--but those are all things we've heard before. I encourage you to tackle the complexities of love, and incorporate more interesting imagery, which would help your argument. This current draft is too simplistic and riddled with cliches, and is therefore unconvincing. Best of luck writing!
