A little experimentation
I suggest shooting with nothing but a Leica and one lens for a year. Shoot one type of black-and-white film (yes, even if you’re completely devoted to color and digital, and hate film and everything it stands for. You don’t have to commit to this forever; it’s an exercise). Pick a single-focal-length 50mm, or 35mm, or 28mm. It doesn’t have to be a “good” lens—anything that appeals to you and that fits the camera will do. Carry the camera with you all day, every day… A year with a single Leica and a single lens, looking at light and ignoring color, will teach you as much about actually seeing photographs as three years in any photo school, and as much as ten or fifteen years (or more) of mucking about buying and selling and shopping for gear like the average hobbyist.

I got it for a steal some time ago on Ebay, and then promptly forgot all about it. However reading the post above and its lengthy follow ups 1 and 2, made me get it out and dust it off in preparation for the exercise suggested by TOP: 1 year with this camera, and black and white film only. It’s not a Leica unfortunately, but it’s what I’ve got and it’ll have to do.
In the spirit of this exercise, the above 2 photos were taken on my D300 with the 50mm AiS at f1.4. I find manual focusing challenging enough, so this will definitely be a step right out of my comfort zone, with a kind of camera I’ve never used before. Quite keen to see how badly i do!
But all this enterprise has worn me out, so for now, my ambitions and I will succumb to the hammering of the flu, and get ourselves into bed.
