I tried waking up at 4 a.m. every morning like Pepsi CEO Indra Nooyi, but I ended up creating a perfect morning routine for myself

Indra Nooyi is best known for being the CEO of PepsiCo, where she is both the first woman and person born outside of the US to hold the role.

She was also named the No. 1 most powerful woman in the world, twice, by Fortune Magazine.

Like many other CEOs and leaders, Nooyi starts her day earlier than everyone else, waking up at 4 a.m. and getting to the office by 7 a.m.

After four weeks of following the morning routines of Jack Dorsey, Arianna Huffington, Barack Obama, and Benjamin Franklin, I was getting accustomed to 5 a.m. starts and exercising before the sun came up.

Waking up at 4 a.m., however, would be a whole new challenge.

It would require going to bed extra early, which meant a radical change in how I structured my day and social commitments.

I didn't manage to wake up at 4 a.m. the entire week. In fact, I only attempted it for three days, and the earliest I managed was 4:15 a.m.

After the experiment, however, I realized that I'd created the perfect morning routine for myself in the process. It just doesn't involve starting at 4 a.m.
