You may feel like you're on top of the world some day but really you're on the bottom rung of your journey to greatness. If you think nothing of yourself but always others then you may be higher than you think. Of course, if you think that you're worthless that is quite selfish because you're still thinking of yourself. You may wish to think that maybe you will be higher in your intelligence if thinking you're of good use to all while in reality everybody may hate you. Although you may have great skills people don't really see what you may accomplish. Only think that you are here for a reason. Know this and see that you are a special person. Be glad that you could experience the world and discover what you may become here in what little or much time you have here.
