It is not our preferences that cause problems but our attachment to them.
We all want to grow and improve our well being and our lives, but few of us want to do the hard work, and have the discipline, that is necessary for us to change and become healthier. You need to commit to following a successful vision and experience what is uncomfortable because that is the only way to self-mastery and self-improvement.
No matter how difficult the past, you can always begin again today.
