lucky? unlucky?

I m not sure whether to say i m lucky or not? every time when i wish for something it won't happen. But after that things realized, but always come at not the right timing......this month i should be having two jobs, one of it was the postponed job from last month. Unfortunately i was unable to take up the job, as i have a few interviews due to attend. I was thinking am I right to give up money for the interviews which still yet to know whether I can get a permanent job a not.....**sigh**
