what to do when you can't rely on your spouse (or don't have a spouse anymore)

I hope this will be a thread for practical tips.  Mine right now:  dealing with yard work (raking).  I'm feeling overwhelmed in terms of time and my physical condition.  (I'm small, not very strong, and perhaps prone to exertion-induced migraine headaches.)  Should I lower my standards for myself or hire someone to help?  If the latter, a service or a neighborhood young person?  

Please feel free to post your suggestions and also your requests for practical guidance if you're lacking a spouse (either because you're not married or you're married but your spouse is AWOL).
