Model from future self – should it be based on what my future self did to get the result or just advice as to what I could/should do in the moment?

For instance – staying on protocol to reach my goal. Is future me saying how I got to goal by staying on protocol? Am I using first or third person, or doesn’t matter?

C. Protocol
T . You/I stayed on protocol to get to goal
F Committed
A. You/I didn’t give in to urges
R You/I reached goal weight
