New challenges for me in 2018. out of ideas

I do nofap, i have taken cold showers for over 100 days now. I have done bungee-jump. I take gingershots. In terms of boldness there is nothing so far i can think of i don't have the courage to embrace. At this moment in my life i would consider myself a cool guy Other than a positivity challenge i'm not sure where else to improve. I have negleted working out, but i have sort of made up for it in the healthy food i eat. I practise my english every day, and i can read rather complicated books now. So is there a challenge you do that strengtens your will-power, or just improving yourself.

 

As cold as it can be.
