A persevering
Have you ever said that you can not achieve what you want?
Most people who can not achieve the desired things in a fast way, lose much interest in it and believe that everything is finished just by failing once. But that's what life is about, to keep trying, that when we think we're defeated, get up and keep trying, because it only fails when you stop trying.
Life is little for me that taught me that, if you do not try hard and you give things over for not seeing you here, you must get up and move forward always, fight for everything and achieve your goals and do not let anyone I told you, until you can arrive because you are the only person who decides what your limits are.
