Exhausted mind, exhausted body, exhausted soul ...

I think i am aging as i started to have physically tireness from time to time... The brain just couldnt function well... it just like a CPU that is hang, and feels doing nothing! I force myself to do more things, but my brain just couldnt process more... Even i insist myself to do the work, end up there is so much careless mistake happens... I started to feel hopeless on myself for being careless, and out of control on my brain, and my body... Shall i look for easier job? Shall i stop torturing myself? OR Shall i give myself a break and resume the reading & and adventures? OR Shall i find a better way to continue earning? Somehow, sometimes, i just feel to let go everything... moving to a spiritual world - chanting for a week to release my mind tireness, my body tireness... etc, etc... amitabha.
