TIRED?

Am loving the late night teas and early morning sahos with You. :)

Just another day someone asked me in church, "Why do you never look tired? Do you really study medicine? My other medic friends always look tired."

I would like to think that it's because I know the importance of waiting on You to renew my strength. Then again, the fact that I'm quite slack probably has something to do with it as well! XD

Help. I need to study.
