Thank you for sharing and don't worry, Jerry, you are not alone at all in this. I have struggled so much with expecting too much of myself lately and I have had a issues with sadness, not feeling like I am enough, etc... Nothing matters more to your or my contribution to this world than being fully present in the moment and connecting with that which is Higher than we are and then living that reality with everything we do. I have made the decision to make this more of a reality in my life and it makes all the difference. We have to "bring the mind into the heart" be unified and become true to our higher aspirations, separate from the ephemeral past and the unknown future.
Blessings to you.
