Are you happy, well-rounded? (dealing w/ depression/lack of motivation)
lotharbot: A lot of people have posted good advice about motivation.  Rather than duplicate that, let me give some alternate/additional thoughts:1) Pay attention to your diet.  Make sure you're getting enough water, and make sure you eat enough veggies and get enough protein and calories overall.  Screwed up body chemistry can make you feel unmotivated and disconnected.  Carry a water bottle (I've got a nice quart-sized stainless steel bottle) and make sure you drink several full bottles a day.2) Pay attention to your sleep schedule, as well as your sleep quality.  Getting not-quite-enough sleep of not-quite-good-enough quality can leave you just a bit lethargic, or over time build up to major apathy.3) Get a physical as well as a psych evaluation.  Don't settle for one or the other.  There are lots of little conditions that can drag you down and leave you with vague emotional weirdnesses.  If the docs find something awry, get it treated, and don't be afraid to go back and ask for changes if the treatment doesn't work; sometimes certain meds just don't work right for certain people.4) Keep exercising.  Sounds like you do some rock climbing; don't give it up without replacing it with something else challenging.OK, so with all that physical stuff in mind -- getting your body right so it's not a drag on your brain -- you might still have a problem.  In large part, "this is what entering adulthood's like", but there are still some things you can do to smooth the transition:A) Have a good, long, serious heart-to-heart with your significant other.  Be totally honest with yourself and her.  You might find some lingering resentment over something you had written off as insignificant, and that can affect your overall mood.B) Remember that the decisions you make now aren't necessarily permanent.  You can change jobs or careers; you can load up the moving truck and head elsewhere; you can start or end various extracurriculars (others have suggested gardening, martial arts, etc.)  Don't be afraid to just try something and revisit it a year down the road (and set yourself up for it -- rent, don't buy, or as lionhearted suggested, travel somewhere cheap and spend a couple months there.)C) Pay attention to the things that make you happy.  Elsewhere on HN I saw a suggestion to make happyfile.txt on your computer and write down things that make you happy each day.  My sister carries a paper notebook and does the same.  Remember, anything that makes you happy goes in the Happy Book -- something a friend says, time spent writing or reading, minor or major accomplishments, religious pursuits, tasty meals, enjoyable HN posts.  The mere act of writing the things down means you think more about them, and over time you may notice patterns and find you really want to make some specific change in your life.For the record, I was 28 and had a pregnant wife when I finally realized the thing I wanted to do most was to be a stay-at-home dad.  I didn't keep a "happy book", but I did pay attention to the amount of joy I derived from working with kids and thinking about family.
