We make promises or agreements with others all the time.
While the level of trust others have with us is determined by our ability to keep our promises, the level of trust we have with ourselves is far more important.
Our ability to keep our word says a lot about who we are and what our values are in life. Think back to all the times you have made a commitment to yourself — to do some form of exercise a few times a week, resist the temptation to have that extra piece of cake, or say no next time someone tries to take advantage of you.
How did it make you feel when you were failed to keep your commitment?
Every time we have not made good on our commitment or promise to ourselves, we lose trust in ourselves to follow through on what we had set out to do. It is hard to keep promises with others if we are unable to keep promises with ourselves.
