A promise to myself

Since I was 12 I want a tattoo but a little one, here there are some exemples of the cutest:

It simbolizes that you promise something, I really love it because it reminds me when I was little and I made "pinky swear" with my friends. For me also represents that I have to remember my promises and never fail to someone who cares about me. And the final reason is evident it's so beautiful and elegant.

"To promise is to give your word about something or guarantee that you will do whatever you are saying you will do."

"Love is endless."

Well I really don't know the real mean of this because I'm too young to know the meaning of love and endless, I know the dictionary definition but I don't know the real significate. Don't misunderstand me, I feel love with my family ( including my pets) and with my friends but I never felt love with a boyfriend.  

I interpreted this tattoo with a very short phrase : life is love. It would mean that for life you have to love, you have to love yourself if you don't do it you can't live nice, you will have a bitter life.
