A Wave is symbolized as one of the strongest forces on earth. so strength for one. also if you read more into it, its about faith, a wave is you against mother nature, you cannot control it, you just have to put your faith into her.
"An arrow can only be shot by being pulled backwards, so when life is dragging you back with tough times or rough times, hold on because you are soon to be launched into better, something great. So stay focused, aim high :) ♥" I love arrow tattoos!
