Heat pump won't help here. During winter heat pump transfers heat into the desired space for warmth. This drives the air inside to be of conditions that cause a cold single pane window to condensate. Think of a cold can of beer on a hot day; it sweats. Same thing here.

Dehumidify or insulate windows using a secondary pane or other product are only solutions.

Doing it scared is how I learned how to skydive. And that unlocked a whole world of possibilities and new experiences for me, to the point that I feel it changed my whole life trajectory and outlook.

All of your examples (except shooting a gun, which i agree is a different scenario for this) all are responses that fear inhibit you from experiencing and learning. Learning new things is scary. For example, I was scared shitless first time I drove on the freeway. Now, I'm beyond proficient at it and ride a motorcycle. I was scared shitless each time I asked my girlfriends out for the first times, they said yes and i got to experience relationships with them. Sometimes you have to overcome the fear by doing it, or life will just pass you by.

To each their own, I guess. Some people are too scared.
