Do u beleive in karma?

I believe in karma. Do you believe what goes around comes around? How long does it take for karma to come around?

When I was around the age 16 years old I went to the Yosemite with my family and my friend and we would use the snowmobile and go up the mountain. One morning we decided to go to Yosemite we found a lake and we were hanging out there for a little while and then me and my cousin decided to go play a trick on the other people that were still in the camping place unloading there stuff. So we went pretty far with the snowmobile and then I was telling my cousin if he wanted to actually do the prank on them he was like yes let’s go for it. We stop in one of the places ware we were going to take the rout and we parked the snowmobile. We had brought along some shovels and we decided to dig a hole in the snow. We had agreed that we were going to dig a hole and cover it with leaves and branches and cover it with a thin layer of snow just to cover the leaves. When we were done we went back to the camping grounds. We told them that we had found a new rout to the mountain that we were heading to. Everyone agreed to follow us. My cousin and I were so into the snow boarding that we forgot about the hole that we had made. We were close to the whole and I totally forgot about the whole and I slammed right into the hole. I was hurt pretty bad I stopped using the snow board because my leg was hurting and I took one of the snow mobiles back to the mountain. When we arrived my cousin was telling everyone how stupid I was because it was my plan to make some one else fall in the hole and I was the one who ended up in the whole. We went back where the trucks were parked and while we were eating the other people decided to use the snow mobiles. In the meanwhile I was resting my injured leg. Then when they came back from using the snow boards and snowmobiles we took off again and we found a place to go hiking we decide to hang around there for a while. After that we decided to race each other and while playing around I pretended that I was about to crash with my friends snowmobile so he would slow down and I could take the lead and if possible he would stop, he got scared and fell of the snow mobile and injured his arm really bad. The next morning we went again and were hanging out again and eating before we decided to take off again and went right back to the lake and caught some fishes, but after that, we went to the mountains and began to race again in the snow but since it was too slippery my back tire was swerving and I lost control of my quad and fell down and scraped my whole arm and legs and half of my face. I was in pain and I felt like was going to go in a panic attack. I felt like crying but I didn’t I was strong and they wanted to take me to the hospital but I told them that I was ok. This is the reason why I believe in karma because I was just playing with my friend and I tried to hurt some one but in the end it was me who ended up getting hurt but because I caused it or tried to harm them, it ended up happening to me too the funny part was that my friend had nothing to do with me getting injured. I think it was all karma. Now I think carefully about the things that I do weather they are right or wrong.
