Good question !
Spiritually...to be more open minded on issues that divide us as christians. I am really struggling with some issues that are now in my Anglican faith.
Physically...I too need 9 - 10 hrs. of sleep. I hate it..I feel like I miss the best part of the day...early morning,just as the sun is coming up and the birds are calling and the earth smells so sweet. I used to be able to enjoy those gifts from God,but I can't any more.
Mentally..I wish I could be self assured. It seems to come so easy for many people. I would love to be able to express my faith,but I have not been able to. I know what I believe..but I can't explain the how's of what I believe.
