If you're asking for main idea, the main idea or thesis statement sentence is sentence 1, where they explain what the passage is about.
Walking down the endless road to my apartment, I just couldn’t stop thinking about work. It was freezing cold and hard to see through the blizzard. The snow beneath me was like an egg shell making crunching noise at every step I took. Finally, I had reached my doorstep. As I wrapped my hand around the frostbitten doorknob, a sweep of fresh warm air thrusted past my body. Struggling, I closed the door behind me.
Hope that helps :)
