Wear your heart on your sleeves. Don't harden your heart to those that you never even gave a chance. Listen to your heart and let it guide you in your decision making. Albus Dumbledore said it best, "The consequences of our actions are so complicated, so diverse, that predicting the future is a very difficult business indeed." If you try to do something like hardening your heart and never giving anyone a chance to know who you truly are just to protect yourself, you're just taking unnecessary precautions. You can never know what will happen. Even if it does turn out the opposite of what you would like, at least you had some good times and memories opposed to not having any if you had built up walls. Follow your heart sounds so cliche, but it's not. You are led to wherever you end up for a reason. Embrace that reason and go out into the world and do it all over again.
Love others with your whole heart. Block out all memories, knowledge of rumors, and things that you may not like about someone and fully devote yourself to knowing who they are. Let them see who you are. People respond to genuineness. If you show love for them, they will be compelled to show you nothing less than that. It becomes so much easier to befriend someone that may not be your first choice of a friend when you look passed all those things.
Don't dwell in the past. Look forward to the future and build yourself up. If you reminisce of the past and what was instead of what could be, you are missing out on life! WAKE UP! Don't feel sorrow for past decisions or outcomes. Be excited that you can make new decisions and write your own book! Look towards the future with a free mind and open arms!
Be yourself. No one likes a fake but a fake. Love who you are and others will too.
Do these things and you will live with no regrets because you have beaten the odds and you have lived your life with full potential.
That's all I have to say today and I feel like it's more than enough.
........For me anyways. :)
