I have a hard time taking time off or letting go of the duties I feel driven to complete.  Doing my duty and fulfilling my obligations to expectations, profession and others tends to trump all, and despite studying Zen and Classical Chinese poetry in 2014 I apparently still have a bad case of the Protestant Work Ethic and ancestral absorption of Jonathan Edwards' 1741 "Angry God" sermon, causing me to expect to be struck down with a lightening bolt the moment if I stop striving.  Or this is all just the personality that drives sends some into law and then to the ulcer doctor (been there, twice, though not recently).
