I learned this decades ago from one of the best IT consultants in the city. I was interning with him, and he told me that for every project he does "one new thing". Typically he tries a new product, a new approach, or just picks up a skill like a specific scripting language.

His thinking is that there's always padding in these projects, so may as well fill the spare time with something that will help him grow. Two new things is too many unknowns and could derail the project, but one new thing is "just right".

I've followed that philosophy ever since.
