Hi,
I agree on: money, organization, nutrition and of course to focus on yourself. Can't even stress the last one enough. People are going to rob your energy if you lose too much focus so stay calm stay focussed and stay happy.
Waking up early is a bit different I think. I tried to wake up at 3,4,5 am for a while and indeed in that phase of my life the most productive time of the day was in the morning between 5 and 10 but it differs from person to person. Right now I feel that I prefer the night time for the most important tasks of the day for example.
So get up early for a while to try if it's your thing. And if not, try the night time and so on :)
