You bet, I can sympathize! When I first started mountain biking, I had bruises, cuts, scrapes, on my legs, on my arms. I remember the first time I drew blood. I was proud! Still....... I could have lived with fewer bruises. As your skills improve, you will see less injuries. Remember to look where you want to go, not at the obstacle. Point your chin ahead down the trail. Follow someone that knows what they are doing and try take their line. Try do what they do. It really helps. Have fun and don't give up!
Time is a companion that goes with us on a journey. It reminds us to cherish each moment, because it will never come again. What we leave behind is not as important as how we have lived." Captain Jean Luc Picard
