Starting with how is always a good idea. Even though you have probably always heard to start with why. The why determines the what, but the how determines what happens. So the why has to be directed behind the how because that defines you.
How you do things is how you are perceived to others. If you focus solely on the how, the why will follow. What comes up will always be up to you. The driving factor should be gut instinct, but do not mistake that for reacting in any situation.
Learning to control your mind and focus your thoughts will teach you to respond rather than react so you can live with no regrets. I remember almost everything that has happened in my life and there are many times that I reacted in a way that causes regrets.
Learn from My Mistakes
I hope to teach others based on the mistakes of my past, to learn from one another and find something from within. The best part of being able to help others shows that you have compassion for others, but when you help others it makes you feel better. Some call it the serotonin effect, I just call it the singularity affect.
You feel empowered because the reward is external the feeling comes from somewhere else. You just helped someone. Regardless of what they thought of you before, they will never forget that.
