We all have heard about the tribal chief who is telling the story to his people of two dogs that are constantly fighting in his mind, and the one he feeds wins. We are a sum total of our habits. Good habits propel us forward and the bad one pull us back. Surprisingly, we act sub-consciously when we act per our habits. So, how do we change our habits? It's quite simple. Action is the food for habits. Feed good habits with corresponding actions and refuse to cooperate with bad ones. This may feel hard in the beginning but efforts will accumulate and it gets easier as we go. Being conscious of our actions (and thoughts) is important. Then comes the will to act. To summarize - Be aware, use your will power to act and have patience. Bonus: Reviewing our day before sleep helps.
