One good communication guideline I can give you, is that, always remember who or what you are speaking to, or about, and pay attention to the situation that you are in. You cannot use the same logic and vocabulary with a group of eight year old floorball players that you would with a team of professional floorball players. You might be able to yell at older players during floorball drills, but you can’t do the same thing to a ten year old floorball player or with a referee during a game.
Above all, always, remember that the world does not circle around you, each floorball game and practice is just a practice, until you start to earn your living on it, then the stakes might be higher.
Every floorball player, parent, spectator, and game official has their own beliefs and sets of priorities. Very few of these people will bend to your desires just because you are a floorball coach. Be prepared to explain what you want and why, this will help you on you floorball coach journey.
