Morning routine with cold plunge and creative work block
Sahil explains that he goes to bed at the same time as his 3-year-old son, around 7:30-8pm, and wakes at 4am. He immediately does a cold plunge in his backyard, which he finds especially challenging in winter. He uses the cold plunge as a form of stress inoculation — he often films a short video while in the plunge to practice speaking under physical stress, which has improved his public speaking. After the plunge, he enters his most important work block of the day, from about 4:30 to 7:30am, before his wife and son wake up. This is when he does his creative work (writing, content creation). He plans the 2-3 priority tasks the night before using a simple note card, so he can start immediately without decision fatigue.
The cold plunge triggers a sympathetic nervous system response, and practicing speaking while cold builds tolerance to stress, which transfers to public speaking. The early morning creative work leverages the brain's peak cognitive function after sleep, and time-blocking reduces context-switching costs.
Sahil shares that he's always been a morning person, but this specific routine evolved over time. He notes that the cold plunge is especially brutal in New York winters, but he finds it gets easier in spring. He also mentions that he doesn't do a specific breathing technique; instead, he uses the time to film a short video or practice speaking, which has helped him become a more confident public speaker.
I get up right around 4:00 every morning. ... I do my cold plunge every morning out in the backyard. ... That morning block from about 4:30 to about 7:30 is my most important work block of the day.
