Life is too short. Life is too short to worry about small, irrelevant, meaningless happenings. Life is too short to spend your days mulling over and constantly thinking about negativity. Life is too short to always assume the worst will happen.
When you assume the worst, you find the worst. You know why? When your mind points out a negative incident and points out a future possible negative incident, you will inherently look for more negative things because of your unconscious thoughts trying to justify your beliefs.
Don't revolve your life talking constantly about negativity, because I guarantee you, people will get tired of it real quick. The attitudes of others can either uplift you or take you down with them. Find poeple who you want to feel truly happy around. You cannot always control what happens to you, but you can control how you view and look at what happens to you. It's all perspective. Is the glass half full or half empty?
When you consciously choose to be happy, you start with your mind. You count your blessings instead of adding up your troubles. YOU chose what affects you and what doesn't. YOU choose what to feel and how to act. You have to remember that everything happens for a reason. What is meant for you won't pass by you and what is meant to be will be. Learn to accept what you can't change, and change what you can't accept.
Don't let one small and irrelevant detail of your day make you think your whole day will go bad. All that does is force you to look for more bad things to confirm your thoughts as I said above. Instead, start your day with self- affirming thoughts and positivity. You hold your own key to happiness, and that starts with your mind.
You ultimately choose your fate of happiness though your unconscious thoughts, so stay positive. The choice is yours.
