Who, by worrying can add a single day to his life?

This little passage "Who by worrying can add a single day to his life" has been plauging me for a long time now, but in the last week the rubber has really met the road. I was in a job situation that really wasn't great, but it was a job and it paid quite well. However it can't be a good job when hearing "it's just not working" from your boss is more of a relief then a pain. The week I have been unemployed I have faced the challenge of not to few job offers, but to many. 4 interviews resulted in two jobs that I will have to wait to hear from, both I am not sure of and both would be great, as well as two "take it or leave it" positions that aren't ideal but there. The dilemma is obvious. Do I risk taking a job I don't really want because the offer is there or do I wait to see if one of the others offers, knowing that I could easily be back at square one. I decided to wait as I feel much more peace about waiting. At least I did. Now I'm stupid worried. The worst part is the fact that I can literally do nothing but go about my life and wait. So to life I go, unsure of everything.
