AM- Weightloss Master Class approach

I have been watching the videos from the masterclass this weekend-I wanted to say binge watching but with notebook in hand and doing the worksheets- As a diamond member- many of these are not new concepts. I want to lose 40 pounds in the next 6 months- This was my same Impossible goal LAST December. It is hard not to get frustrated with myself.
But I am determined to keep at this and maybe this deliberate course will be the ticket. Do you recommend I do it month by month -or can I go faster through the material? ( I know I CAN do whatever I want- but looking for your opinion)
Thanks, Anne
