There's many types of focus and meditation. Meditation is like swimming. People can study, discuss, and pontificate about swimming, it's all academic until we're in the water sloshing around ourselves.

In the case of mindfulness that is triggering some dismissiveness on your part, there is also abstract, settled, or awareness typed meditation. The latter, focusing on abstract, awareness of awareness (being a witness to your thoughts) without directing them can be just as useful to unlock creativity in day to day life.

Some meditative experiences are very similar to flow and allows the ability to slip into flow that much easier. Some folks can slip into meditation just sitting at their desk by closing their eyes and come out a few minutes later settled and focus in hand for something.
