Changing one’s habitual way of living becomes tough if your Mind resists the change too much. You may have willingness to change, but the Mind may not support you easily in the process.
I have seen this pattern with my clients and also with me at times. We (to be specific, our Mind) seek permanence. We are used to the way we live (even though the current way of living is not supporting us). Changing it may not be comfortable for our mind. We may go blank during this time! We feel that our mind is jammed. Some may feel extremely tired even though they have not done any major physical or mental work. You may not get any new ideas or may not understand what is going on with and around you.
This feeling state prevents you from progressing in the right direction. You may be attempting to act against your habitual way of acting, but the mind may not go with you. It will go blank and you may feel alienated for sometime.
