It's not bad, but it isn't what everyone on earth should be striving for.
Today, I finally got the exam results I had been looking forward to for, let's just say a LONG time.
And hey, I got straight As! But I wasn't as happy as I had imagined, though I felt really satisfied with myself. I never really thought I could do it, but there's proof that I can.. :) I'm really really really happy, sure. But this is really just short term happiness. Life goes on. Sure, maybe one day in the future I might look back on it and feel proud (seeing as everyone's proud of me now), but that's just as far as it goes. Still, I'm glad I can fill this little chapter of my life with this memory. This is a great accomplishment,and I intend for more to come.
So what I'm trying to say is, do something that you know will make you happy for life, not just a day, a month or a year. Short term happiness isn't bad. There's just more to life than that.
