With regard to the job search, work on reducing stress. That carefree attitude that helps in getting job offers is directly (and sometimes geometrically) proportional to your ability to recognize all of the good things you have at any given moment. Sometimes that includes changing (not lowering) expectations.
I say all of this with the caveat that 1) fame and fortune are overrated as human goods, especially by young people; and 2) I am neither famous nor wealthy, but I am exceedingly happy with my life compared to my 20s. I'm now in my 50s and generally successful in curbing my urge to bail out my 28-year-old daughter out of the messes she sometimes makes.
Edit: But I have been there a couple of times where it was help her or she ends up on the streets.
