Smile & discount it. I coached soccer for boys & girls from ages 5 to 15 and I had to deal with negative feelings a lot. We are all brought up differently & we all face different experiences in life. Many of these life experiences breed negative feelings within about oneself and others.
The reason I mention coaching kids soccer is because I took it on as my job as coach, and a parent, to help the kids overcome any negative feelings they had about themselves and others. I stress to the kids to that they can play any position and then I assess their abilities and work on improving their weaknesses. It is usually the weaknesses that scare them from attempting to play certain positions. Once I help them improve, they feel better about themselves & more positive they can succeed. I also allow encourage them b y telling them what they did right more than what they did wrong. Kids need encouragement to do well & enjoy doing it. I find my philosophy differs from some coaches who only choose the kids with superior talent to play first string, all the time & certain positions. I believe a good coach breeds talent & a positive attitude, (s)he doesn't merely look for talent & discard everyone else.
I also try to stress a positive attitude about the game, the referees & the other team. I tell the kids to accept whatever call the referee makes & I will as well and just play the game; it all evens out in the end. I also stress we are playing to win, but we are playing to enjoy the game; to have fun. And so is the other team, so compete against ourselves, to play better, not to beat the other team.
This year I coached for the first time after taking a break to watch the game for four years. I coached a girls U15 team; a group of girls who had not won more than 2 games a season in 4 years. We ended with a winning season & all throughout the girls were excited to play and everyone got along great and had great fun. A positive attitude made for a great season. Fun for them & fun for me.
