Any penetration testers here? Looking for some (career) advices and tips :)

Grandmother: 'So do you use 1's and 0's for Programming?'

Mom: 'fix my Computer/Internet/handy/printer'

So the Weekend ist coming Up (and at thursday the next Semester in university)

I googled for it but didnt found anything great: does anybody of you know actually a good drinking Game For Programming? ;)

So, i decided to Start making an Android App (quite a big Project to me), so i we're Reading books und Programming Yesterday for 12, today for 10 hours, everything worked Out perfectly, i fehlt great.
(But, Thats the rule, never feel too confident)

So i wanted to Put the Last Activity in my App, chanhed the XML etc.
At the end i thought i should run it one Last Time before i shutdown my PC.
Well, Error in my XML, tried to fix it for 1 hour (quiet a Long Time for 8 lines of Code), didnt Work.
I pressed Ctrl+z until it reached the Point where it Last Time worked... Still doesnt Work.

So, i am quiet pissed Off, and sleepy.
My Dilemma, eat and sleep? Or try to fix everything...
