Fear is Fuel.
Use it or waste it.
My first sparring session i was so scared i went to the toilets three times in fifteen minutes.

Boxing is a great sport. Certainly it is more aggresive than any ball sports and the aim is to make as much of a physical impression on the opponent as possible, but the techniques involved, the sciences of movement and the psychology of ring generalship play a much larger part than simply hurting your adversary.

Try it. You will train first, no contact. And then you will no if it's for you. It may not suit you, you may dislike it, but its a small risk for a potentially great reward. When you feel that all the training is worth it, all the effort is justified and you feel like you just want to get in there and fight. Thats a coming of age a can tell you.
