I don't think I really have a survival kit as such, although if we run out of tea, there's definitely a problem.
What I do have are a few tactics. One is speaking up when things start to feel heavy. I think a lot of us are conditioned to come up with solutions rather than problems, but during really busy periods it's easy to lose perspective. Sometimes just saying something out loud to a trusted colleague is enough to bring a bit of clarity.
I'm also a big believer in carving out moments to decompress, both with and without the team. A quick drink after work or even a lunchtime walk around the block with a colleague can make a huge difference. And Friday nights with my family after a busy week are non-negotiable for me.
I always make sure there's a plan for after the busy period too, not necessarily as a reward, but as a reminder that the pace won't last forever and there'll be time to pause and recharge. For me, that usually means getting out into nature - ideally a quick camping trip, weather permitting!
