PhD coaching

I submitted my rough draft proposal to my supervisor, yesterday. I realize there are still lots of things that needs to be done. However, I feel really happy with my level of productivity this week. How do I keep this up?
So I got up this morning a little later than my usual time, and said I need to work my PhD. I do not want to stop my productivity streak. So I got on the Internet to google what is the expected time I should spend on my PhD a week. For full time student, you need to spend 35 hours a week. For part-time student, I guess you can say about 15 -20 hours a week.
I work full-time. I lecture at UiTM, and working on my PhD. Currently, my schedule is a bit flexible. So, I would like to think that I am working on the PhD full time and working part-time. My goal is to finish within a 2 years time frame.
Based on these expected hours for a 3 years PhD program, you need to spend 5,460 hours. So, you are trying to finish a 3 year program in 2 years you need to spend 52.5 hours a week. There are 24 hours in a day. This can be done, but you will need a system.
I figure I need to spend 8 hours a day for 6 days and 4.5 hours for one day. I will spend 8 hours for the PhD on Sunday till Friday, and spend 4.5 on Saturday. So, this is the formula I got for managing your time for a successful finish. I also found a website on PhD coaching. I thought this was a great website, a must read for everyone. It is called the three month thesis. The website is www.3monththesis.com.
