Be an original in a world full of copycats. Live your life as you want not the life someone wants you to just to make him/her happy. Even if you are are in a relationship, always remember that you are your own person, not a copycat of the person you are with. Yes, you may have similar interests, backgrounds, shared experiences, but you are still you. We are all unique in some way, don’t lose that. Ever. You can stay true to the one you love and still stay true to you, the one person you should love above all others.
And yes, I still need to remind myself of this advice too.
