Question: How can we distinguish between the two impacts of the Creator on us to choose which to say first: “There is none else besides Him” or “If I am not for myself, who is for me”?

Answer: You need to cleanse your heart a little, and then you will understand the attitude of the Creator toward you.

Question: In which case will I have the opportunity to say: “If I am not for myself, who is for me”? Because it is always convenient for me to say: “There is none else besides Him.”

Answer: Of course, that is always better.
