'No Porn at Work,' and 16 Other Bizarre Goals People Committed to Humans are strange beasts. The proof is in this bewildering list, courtesy of the goal-getters at motivational app StickK.

Humans are tenacious beings. We're flawed and we know it and we strive to be better. Then we fail and try again.

In the broader scope, the aspects about ourselves we strive to improve often include the usual stuff -- waking up earlier to squeeze more productivity out of our days, exercising more often to stay fit and live longer and saving money to live comfortably after retirement. Nothing too out there.

Then there's the just plain weird. For example, when people pledge to try not to watch porn at work, not to bang their head when raging out and not speaking excessively slowly to foreigners. You can't make this stuff up. We're certainly not. These truly are some of the more bizarre commitments people have made when using StickK, a motivational goal-tracking app designed by behavioral economists at Yale University.

Similar to betting, StickK users put money down toward a personal-improvement commitment. If they don't keep their commitment, they give the money away to a person of their choosing (friend or foe), or to charity. If they stick to it and succeed, the money is theirs to keep, along with their pride.

"Attaching a financial incentive to your personal goals reinforces your resolve and willpower and increases your likelihood of success," StickK co-founder and CEO Jordan Goldberg tells Entrepreneur. He claims people who use StickK are three times more likely to succeed in achieving their goals than those who don't. (Full disclosure, it worked for one Entrepreneur reporter.)

But let's get back to the bizarre stuff users pledge to do with the app, shall we? Courtesy of StickK, here are 17 quirky and/or disturbing goals people have committed to. They were shared with us anonymously.
