Communication starts immediately in the first meeting with your team, players, new people, other floorball coaches, referees etc. the first impressions counts! Dress well, hold your head up high, look into their eyes when you are speaking, and always speak slowly and clearly. Treat everyone with the respect that you hope to earn or get back. (body language)

Listen when others speak and consider what they have to say before you respond. So you respond on the right thing. Ask questions as “receiver”, to secure that you have understood the message from the “sender”.
Make sure that you understand their point of view before continuing the conversation.  When you disagree, do so respectfully, clearly state your case and avoid repeating the same points over and over.
