Something to keep you away. To limit your potential, to stop you. Something that only exists to cease your progress, something that only is there as a gate, a thing that weeds out the weak. Sometimes there are doors in your life, doors that block your entrance, doors that are locked. But if the door has a keyhole? Find the key, push forward and accomplish anything. Break limits, move forward. You can persevere. Study harder, work harder, invest time. Time is a gift, nothing comes without time. Remember one thing: All doors require time to be opened, so be prepared to use your time wisely. And if you don't? Who knows.
