It is not the mountain we conquer, but ourselves.
-- Sir Edmund Hillary
Life goes through changes so fast, you think your life is great, than one of your best friends dies. Then you think you found someone you truly love, only to figure out, she doesn't love you back. You cry and cry and cry, but nothing changes. You realize, that you must accept things for what they are, and what they have made you become. Everything in life changes you in some way. Even the smallest things. If you do not accept these changes, you do not accept yourself. For through these changes brings new and greater things to you, making you wiser, as time progresses. To avoid these changes is a loss. You only live your life once. Do not waste a minute of it avoiding things. Let them come to you, and learn from them. There's always tomorrow.
To your friends, you're like a trash bag; they'll use you for a little bit, then they'll throw you out.
