  1. Let Go

    #862 · February 18, 2011

    Let Go

    After years of trying various methods, I broke this habit by pitting my impatience against my laziness. I decoupled the action and the neurological reward by setting up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected.

  2. Complex Conjugate

    #849 · January 19, 2011

    Complex Conjugate

    Fun fact: if you say this every time a professor does something to a complex-number equation that drops the imaginary part, they'll eventually move the class to another room and tell everyone else except you.

  3. Positive Attitude

    #828 · December 1, 2010

    Positive Attitude

    Having a positive attitude is almost tautologically good for your mental health, and extreme stress can hurt your immune system, but that doesn't mean you should feel like shit for feeling like shit.

  4. Constructive

    #810 · October 25, 2010

    Constructive

    And what about all the people who won't be able to join the community because they're terrible at making helpful and constructive co-- ... oh.

  5. Connected

    #807 · October 18, 2010

    Connected

    Or love in general, for that matter. It just leads to the idea that either your love is pure, perfect, and eternal, and you are storybook-compatible in every way with no problems, or you're LYING when you say 'I love you'.

  6. Bad Ex

    #796 · September 22, 2010

    Bad Ex

    Since the goatee, glasses, and Seltzer & Friedberg DVD collection didn't tip you off, there will be a $20 negligence charge for this service.

  7. Still No Sleep

    #776 · August 6, 2010

    Still No Sleep

    I'm not listening to you. I mean, what does a SQUIRREL know about mental health?

  8. 1996

    #768 · July 19, 2010

    1996

    College Board issues aside, I have fond memories of TI-BASIC, writing in it a 3D graphing engine and a stock market analyzer. With enough patience, I could make anything ... but friends. (Although with my chatterbot experiments, I certainly tried.)

  9. DFS

    #761 · July 2, 2010

    DFS

    A breadth-first search makes a lot of sense for dating in general, actually; it suggests dating a bunch of people casually before getting serious, rather than having a series of five-year relationships one after the other.

  10. 3x9

    #759 · June 28, 2010

    3x9

    Handy exam trick: when you know the answer but not the correct derivation, derive blindly forward from the givens and backward from the answer, and join the chains once the equations start looking similar. Sometimes the graders don't notice the seam.

  11. Principle of Explosion

    #704 · February 19, 2010

    You want me to pick up waffle cones? Oh, right, for the wine. One sec, let me just derive your son's credit card number and I'll be on my way.

  16. Revolutionary

    #675 · December 14, 2009

    Revolutionary

    I mean, what's more likely -- that I have uncovered fundamental flaws in this field that no one in it has ever thought about, or that I need to read a little more? Hint: it's the one that involves less work.

  17. Pandora

    #668 · November 27, 2009

    Pandora

    What? Oh, no, the 'Enchanted' soundtrack was just playing because Pandora's algorithms are terrible. [silence] ... (quietly) That's how you knooooooow ...

  26. Fermirotica
