Can I peek a bit into the future before I decide? Maybe I have a girlfriend in the future. Maybe I have a cat. MAYBE THEY INVENTED TEA THAT REQUIRES NO BREWING TIME!
Otherwise I'm going into the past and winning myself the lottery on my 18th birthday. Maybe I'd act on some of the oh so blatant hints I got from one of the few girls who acknowledged my existence in high school. I was pretty oblivious back then...
