My approach is to think about the base salary as the "real salary" and the bonus as "lottery".
I negotiate the base salary as high as I need to make. When discussing bonuses, I politely pretend to be interested, but what I actually think is "this is just some imaginary number, that maybe I could get if I win a lottery, which probably is not going to happen".
My family budget is calculated on the base salary. If I get a bonus, I will probably immediately move it to a savings account, or maybe use it as an extra payment on mortgage, to get it out of sight.
