If you change yourself you will change the world. If you change how you think you will change how you feel and what actions you take. And so the world around you will change. The change within can allow you to take action in ways you wouldn't have or even thought about.
You are in control
As you realize no one outside of yourself can actually control how you fell you can start to incorporate this thinking into your daily life and develop it as a thought habit. A habit that you can grow stronger and stronger and stronger over time.
Forgive and let go
If you don't forgive then you let the past and another person control how you feel. By forgiving you release yourself from these bonds.
Without taking action very little will be done. To really get where you want to go and to really understand yourself You have to take action and translate knowledge into results.
Take care of this moment
When you are in the present moment you don't worry about the next moment that you can't control. Imagining negative future consequences – or reflecting on past failures caused your actions to lose its power. Reconnecting with and staying in the now is a mental habit – a sort of muscle – that you grow. Over time it becomes more powerful and makes it easier to slip into the present moment.
