Once Bitten Twice Shy - this principle did not work for me

crappy judgement while navigating a curve, coupled with overconfidence. During last christmas, I crashed into the barrier while skiing down a slope. During end Jan this year, I crashed into the barrier, seperating the bike track from the canal. Damage - 7 blue blacks due to my own stupidity. Lesson learnt, never speed while biking on unfamiliar territory not matter how confident you are. Slow down while navigating a bend and break when you see an obstacle infront!
