A certain level of asceticism is possible in a city; more, perhaps, than usual, as the distractions and temptations are more abundant here. I mostly just abstain from eating junk food, consuming alcohol, watching TV, and wasting money away on frivolities. Some days I'll fast, just as an extra measure. My only indulgence is playing video games. Though I've cut back on this quite a bit in the past while, I'm loathe to eliminate it from my life entirely. I'm quite good at acts of omission. The only thing I actively do to discipline myself is working out. While most people I know quite enjoy being active, I hate every minute of it.
As for hermiticism, that's far less realistic, especially considering I'm working full time as a cashier. Every interaction with other people for the past 9 years has done nothing but drain me and make me more asocial. 8 hours a day of that is too much for me. Outside of work, and seeing my family at home, I rarely see any humans.
Haven't visited many places; as I'm still rather young, I don't have much freedom, and can't go off adventuring throughout BC. I have hiked Mt. Garibaldi in High School, and camped at Shannon Falls, but that's about the extent of my travels here. Sorry to disappoint. And I hope you think something of me by now, whether it be good or bad. There's nothing wrong with forming quick first impressions, provided you're equally as quick to amend them.
