If what the person is saying is not true, look puzzled and say something like, "What does that have to do with my wanting a job that makes me $1,000,000?" Be impatient, shake your head slightly side-to-side in a vague "No" movement so they get the hint you feel they are interrupting and their opinion is not on target or something you are interested in listening to.
If what the person is saying is true but you don't want to hear it right now, remind yourself that you are working on whatever issue they have brought up, in your own way and time and that you are perfectly happy with how you are doing so in
your life. Interrupt them to say something like, "Thank you for your opinion but right now I am interested in talking about what kind of job would make me $1,000 a week so I could have $1,000 a month to pay rent/mortgage; $1,000 for car, food, and utilities; $1,000 for saving; and $1,000 just for Me to spend as my little heart desires!
