if you live near a body of a water, there's a good chance someone can offer you a canoe to rent. find them, rent it and explore said body of water. if you live in san francisco, you've got even more options. if you live in san francisco and feel up to a three hour drive, may i suggest traveling north to the big river estuary in mendocino where the fine lads of catchacanoe will let you get on a boat. don't fall asleep and drift into the ocean though, they don't like that very much.
take a ride to your nearest beach on a less desirable day - the foggier, the moodier, the overcastier the better. enjoy exploring the eerie atmosphere, get lost in your solitude and consider the stark contrast of the beach on a sunny day. if i were you, i would avoid swimming, drowning and falling off cliffs. no one will find you.
san francisco: grab a group of good pals and head north over the golden gate bridge to the top of mount tam. follow the narrow, curvy roads up and up through the hills and trees. pick one of the many scenic places to stop and hike on up just before sunset. may i suggest a nice bottle of wine to sip as the sun sets. be sure to drink in moderation unless you actually want the hike down to get ugly.
whenever you wander about, take a moment to find reflections in unexpected places and unconventional surfaces. consider how objects and faces transform and take color depending on the type of surface you're looking at. i'd refrain from becoming too curious around water, especially if you're really interested in staying dry.
book yourself an adventure to distant lands exclusively by yourself. the further, the better. take lots of photos, meet lots of people, and break lots of your own personal rules. i'd like to suggest the beautiful city of amsterdam as the location of your solo adventure. it's clean, friendly and full of activities. if you aren't very resourceful, are a little bit shy, or unwilling to try something new, then you'll probably have a really, really bad time. don't die!
every week map out a different way to get to work, school, or that other thing you do regularly during the day and night. if you take the bus, take a different route, or get off a few stops earlier/later to explore the areas around you. if you walk, keep walking cause that's pretty cool, but take different paths to get there. if you drive, take a bike. if you take a bike, walk. if you take a taxi, stop doing that.
if you're lucky enough to have access to your roof, take a moment to go up there at midnight and observe the environment around you. for an extra special treat, wait to do this during a full moon and bring some music with you. two things to note: if you fall, not my fault and if someone thinks you're a robber, jump.
navigate to your nearest ridiculously large hill. in san francisco, may i suggest the pacific heights / russian hill area. once at the bottom, begin to walk up the hill backwards for a different experience and a more spectacular view of your city. in the event a small dog comes running along behind you and you fall down because you're directionally off, don't say i didn't warn you.
organize as much as you as you possibly can by color including the ever popular mobile computing device, the iphone. try out other chromatic organization platforms like your macbook dock icons, your bookshelf, or your closet. take pride in yourself when everyone steals your idea, i won't tell anyone where you got it.
