Passion, desire, drive, pretty much all the same, and that may very well depend on what you are talking about. As far as I can tell they are the same.
Take a career for instance. If you go to college with the passion for a certain field of study you are going to go at it with the desire needed to become an expert in that particular field. The drive you have to be the best will then hopefully fuel you throughout your life.
In love, your desire for a certain someone can spark the drive to show the object of your affection that you are passionate about there needs and want them to be happy.
If you should develop the drive to go outside you comfort zone. You will need the passion to excel and the desire to succeed, so that your dreams will not be crushed.
The following is just some of the evidence of my Passion, Desire, Drive.
My Evening Prayers
As I lay me down to sleep
I pray my love in your heart
Until beside you each day
I may savor
I pray my love ne’er loses
I promise to belay your
doubts and fears
I will cause you never
of pain nor tears
