Om Swami
Why do I break my promises to myself, like one drink or a short break, and how do I fix it?
Don't overestimate your mind; build strength with small resolutions
We must not underestimate the power of our addictive tendencies. Many people promise themselves one drink or a 10-minute break, but it turns into six or seven drinks, or into hours. This means the strength of the mind has been overestimated. You can build that strength over a period of time by taking on smaller resolutions and sticking to them, and then the mind starts to listen to you.
You have overestimated the strength of your own mind. At this stage it takes stamina. You can build that strength over time by taking on smaller resolutions and sticking to them.
