Regret is a poison that individuals choose and allow to intoxicate themsleves with, much in the same way that one may choose to intoxicate themselves with alcohol. Over time, the body will relieve itself of the alcohol that has intoxicated the indiviudal, and they will become free of its effects and become sober. The same can be said about the mind and its ability to relieve itself of the intoxication of regret by accepting that what's done is done. You cannot change what has all ready happened. Do not dwell on it. You can love it or hate it. If you hate it, you will be consumed with negative emotions and it will be difficult to expand your mind and become great in the future.
The mind must be directed toward love and total acceptance for past events; how they've shaped you, bettered you, and evolved you. Move on, further down the road. If you keep looking back, you will continue to stumble.
I am not under the influence of regret. I live free of it.
