Enjoy the moment you are in and each moment that follows, for a moment only has its own time to be and never will it be again. Enjoy and celebrate who you are, you are the only person like you in all existence. Once your time is up you shall not be again, a lifetime is but a small amount of time to exist. So do not doubt yourself and do not cheat yourself from becoming the best you that you can be. Worry little about if others like or accept you, fo there will always be those that oppose and/or dislike you. Just the same there will be many who will love and accept you for who you are, So walk away from those who shun you and embrace those that do. Think no ill thoughts of those who dislike you. Life is way too short to waste energy trying to convince someone to like you, so use that time and energy on better things.
This is your moment, this is your life! Cherish it, embrace it and constantly work at making each moment more memorable than the last. This life is a gift, Celebrate it, live it and be thankful for this chance to exist.
