Joseph S Stevens Here are my thoughts about this topic:
Learning by doing - Building a team culture where people do mistakes is a really hard task to do, but it demands a consistent approach. Encourage them to fail. If everything worked right, we'd all be out of a job, wouldn't we?
Team effort - Teamwork makes the dream work. By working closely enough, everyone will be able to be supportive once the failure occurs. On my first task, I failed miserably. Lucky enough, I had people who started laughing and encouraged me to fail even more.
Knockbacks - Someone will always come and knock us on the ground. And yes... it is demotivating. But you have a chance to mitigate this pressure. This will 100% happen at some point, and you know it yourself. Get your team prepared in advance and it wouldn't be as big of a problem.
Bonding as a team - Look it on a bright side... If you made a mistake, you just found out one way that doesn't work. Grab a beer🍺 and celebrate! If it worked perfectly, well, team dinner time!
Stress release - Find something that will completely shift your thoughts from work. For me, music, football, basketball, and longer walks are functioning very well (not to mention a couple of beers🍺🍻).
And remember one thing: just because you're lead doesn't mean that everything needs to come from you. Be an example that you want your teammates to be.
Hope you find this useful!
