Stick to

I have seen all the fancy electric toothbrushes, but I'm going to stick to the old-fashioned kind.

If you stick to your studies, you will continue to improve.

When I did newspaper work in the 1950s I always found it hard to initiate criticism of a person. Now, in the late 1970s, I suddenly find it has become hard to praise a person. Take, for example, the case of Liu Jie, an inspector of the neighborhood registry in the Daxing’anling district of Heilongjiang, who was praised in the press for sticking to principles. She also had the support of the Provincial Party Committee. But it was precisely the commendation of the Party newspaper that brought calamity upon her, and the support of the provincial leadership was of no use in breaking the siege that befell her.

What I get from work makes me a better mother, and what I get from being a mother makes me a better journalist. At least that's my story and I'm sticking to it.

The suspect doubled back through an alley, but the detective stuck to him like glue.
