You don't stay the same forever. You'll grown. But on the way you’ll realize how wrong you can be about a person and you’ll learn who always will be there for you. You’ll loose friends and you’ll find new ones. That’s how it works. Just remember that you should never regret something that once made you smile. Don't let people hurt you, but when that happens, try to learn from your mistakes and make yourself a stronger person. People will let you down. Don't overthink things. Life's the longest we'll ever do, but it's to short to just think and don't make progress. You'll regret it. Don't create problems that's not ever there because it'll only make things worse. This is LIFE. It's only up to you what you'll do with it, so make the best of it.
Let your dreams be bigger than you fears, and your actions be louder than your words.
