<human>: Can you condense the text into three sentences or less?

I'm 23, graduated in May, and I work in retail right now as an Assistant Manager.  It's by no means what I want to do with my life, I never saw myself in that role, and I am praying daily for a new job (I've been applying for a lot of reasons, but with little luck).  In any case, I was complaining and the gist of my complaints was this:  I feel like I bust my ass, work really hard, but I feel like I'm the only one.  My dad started giving me the usual advice: pointed out that it isn't in our (my family/cultures) nature to do anything but our best, which is true.  He also said that I should be very grateful to have a job, and I COMPLETELY am.  But that doesn't mean I can't complain every once in a while, right (this was the first time I'd complained to my dad since I got the job 6 months ago)?  And then he hit me with something really unexpected.  

He said, "The one thing I've learned is that there are two types of people in the world, those that bust their asses and those that just don't give a fuck.  And all I know is that both end up at the same place at the end, except one is happier.  If I had to do it all over again, I'd never give a fuck."  

I was completely shocked.  I've always wanted to believe that I would someday get to a point where I would be among peers/coworkers that tried as hard as I did.  I knew that wouldn't be entirely true, but it's really sad to me that he feels this way when he's been through so much more than I have.  I don't want to lose hope for a fulfilling job with people I enjoy being around most of the time.  I don't want to just get a job and be there every day counting minutes until it's time to go home.  Should I start preparing myself for being miserable at work forever?  Or can I hold on to some hope, even just a little bit.
<bot>: I work really hard but I feel like it gets me nothing.  My dad says I should just stop giving a fuck.
