Did you struggle with imposter syndrome or embarrassment when you first started?
Honestly, your first 2 or 3 games are gonna be rough, especially on offense. You’re gonna constantly be confused about where to stand, you’re gonna be stepping on people’s feet, and the scrum half is gonna constantly be yelling at you to move out of the way - don’t take any of it personally, and don’t be embarrassed because everyone you’re playing with was in the exact same situation when they started playing. It will click eventually, don’t worry.
