I am someone who wakes up every day around 4:30 – 5 am.
However, it is less about what time you wake up, it is about what you do when you wake up.

Do you go through your mails first thing in the morning?
Or see how many likes you have gathered?
Or check if your friend has seen your message?

This will anyway set up your day for a failure.

As much as waking up early is a great habit, owning your first 2-3 hours for yourself is the best way to set up for success in the outside world.

The outside world is simply a reflection of the inside world.
