A tango, chacha is not as unpredictable...
Tango because it's a tough discipline but you don't give up. And sometimes it can be a chacha, having the system of stepping forwards and backwards in terms of success. Some days are diamonds somedays are stones.
Quote that from a John Denver song "Somedays are diamonds somedays are stone".
More like the "Peppermint Twist" or maybe the "Bossa Nova" :]
