Heck, some of us can make those kind of mistakes when we're not jet-lagged. It's just that I hate to lose a roll of film, as you do also.
I actually have a Canonet QL17, but the light seals are screwed up at the moment. Gotta get around to fixing those so I may reenter rangefinder land.
Ash, Sidearm, do not pine for for Swedish perfection. Take one week's lunch money down to the camera store and buy a Canonet QL17 for about $25. Yes, it was made 40 years ago, but there are millions out there, and most of them still work. You will have a pro-quality lens in a fast, practical camera body. Not as wide as a 60 on 6x6, of course, but wide enough to feel wide if you use it thoughtfully. And, competitive with any single camera-lens combination I can think of .... don't let lens lust destroy your young life, Sidearm! Go and Shoot!
Hm, as for an assignment for yourself, have you seen the movie "Smoke" with Harvey Keitel? Check it out, I cannot find a better and interesting example of a photographic assignment.
I let myself guided by what I see around me in other words I find that every type of environment has some kind of appeal (photographic that is); As suggested I carry a camera with me at all times and shoot what inspires me, whether landscape, cityscape or people. Love for the medium and a genuine pleasure to share what I see/ feel with other people is what drives me out of the house. Unfortunately having to work 9-5 leaves me very little time to shoot
You will likely get more suggestions by posting this in the forum. Or doing a search--I do believe this topic has come up before.
Here is my suggestion--just carry a camera with you at all times (I carry a Holga) and shoot something every day, regardless of how mundane it may seem. I find that after a few rolls of this, a "theme" appears than I can focus on.
Best wishes to you as well.
