Shoot faster. Think less, react more. Don't put things in the center of the frame so much. Use the ability to see the edges to your advantage.
Camera doesn't matter unless it's a hindrance to above.
Many people, myself included, came to the Leica not so much because of what if offers feature wise but because everything else feels like a hindrance to shooting. I avoided it for as long as I could shooting with point and shoots, small SLRs etc till I tried one and realized it has just the stuff I want and nothing else to get in the way of seeing and shooting.
