If...

Last class I learned about first conditional... This subject is easy, but like always, I was traveling at class. I understood, however I have to be sincere, part of my understanding was because I've studied before! Although I though a thing that is true. The world today are full of "IF", If something happen, I will do something. If they do, I will do.. GUYS STOP, forget about "IF", do the things that you wanna do; Do the thing that you have to do.
