Regular participation is how a team becomes a team. If work, family, or transportation affects your availability, tell a coach early.
Be friendly and courteous. Use clean language. Practice humility. Say "I don't know" and "I was wrong" when they're true. Leave school and politics at the door.
See what needs doing and do it. If you cannot find the next task, ask. When in doubt, put tools away, sort parts, clean up scraps.
Let your "yes" be yes, your "no" be no, and your "maybe" have a clear reason. Be dependable so teammates can plan around your commitments.
"My part works" is a hypothesis to test. Ask what happened and where our assumptions disagreed.
"I forgot." "I miscounted." "I dropped it." Report the mistake, correct what you can, and help prevent it from happening again.
Big ideas require a scope, a deadline, and a fallback. "Trust me, I'll get it done" is not a plan.
Treat everyone with respect. Learn people's names, share what you know, and lead by example.
Match your volume to the room. Allow silence between comments.
Phones are for build references and build photos, not entertainment.
