Turnaround time
I'm not a full-on mountaineer, but I've done a good amount of hiking in dangerous conditions, and one important rule when going for a summit is to establish your turnaround time before starting out. That's the time at which, even if the summit is in sight, you turn around. When you're high up on a peak, drained yet excited, yearning to be able to say that you climbed whatever mountain it is, you're going to make bad decisions. The turnaround time takes that decision out of your fatigue-and-hypoxia-addled brain and instead lets it be handled by your more rational, safety-minded everyday brain. It isn't a perfect system, but it's an important rule nonetheless, and the same logic can be extended to other avenues of life.
The current situation in the US is... not great. Every day the current administration does more unprecedented, dangerous things, and commits more crimes. It can be easy to see all of it, and see the complete failure of the opposition party to stand up and try to stop it, and just shut down. It's easy to lose track of how bad things are getting, compared with how they used to be[1]. To quote the late Mario Savio:
There is a time when the operation of the machine becomes so odious, makes you so sick at heart, that you can't take part! You can't even passively take part! And you've got to put your bodies upon the gears and upon the wheels, upon the levers, upon all the apparatus, and you've got to make it stop! And you've got to indicate to the people who run it, to the people who own it, that unless you're free, the machine will be prevented from working at all!
Each and every one of us needs to decide what that time is, what line needs to be crossed before we stop grumbling through our day-to-day lives and stand up. You don't need to tell anyone what that line is[2][3], you only need to tell yourself. What's important is that you decide what that threshold is in advance, because otherwise you'll keep pushing for that goal of pretending this is all normal politics, that you just need to vote harder next time, only for night to fall and a storm to roll in while you're still trudging along, exposed on the ridge, miles from shelter.
[1] The federal government is being dismantled by a billionaire illegal immigrant pissed about being investigated for all the laws he keeps breaking, and half of the country is cheering. It's the same half of the country cheering the creation of camps in which we can concentrate immigrants prior to deportation (if only there were a shorter way to phrase that...). The federal government is also rapidly becoming anti-vaccine as an outbreak of measles, which the US eliminated 25 years ago, spreads and kills in the southwest. The Secretary of Defense purged the JAG corps and is replacing it with lackeys willing to sanction war crimes. The President is friendlier with Russia than with any of the US's allies. I could go on, but you get the idea.
[2] From an opsec standpoint it's best if you don't, especially not via any potentially discoverable medium.
[3] It also doesn't need to be a single line - different levels of response need different inciting thresholds. The state of the world that justifies marching in the streets is a different one than justifies storming the Capitol.
