one-track mind
Thinks only one
A one-track mind is fixated on a single subject, unable or unwilling to think about anything else.
The phrase usually carries mild criticism—someone with a one-track mind about work neglects other aspects of life: All he thinks about is money—total one-track mind.
Often the implied obsession is sex.
