Spend your finite mental energy where you have control

The speaker describes focus as mental energy, a limited resource much like the physical energy that leaves you exhausted after a long or hot day. Concentration and directing attention require paying out that mental energy. If it is invested in things you have no control over or can't change, he says there is a very high likelihood of running out and struggling coming down the stretch, on the last three or four holes that often demand the highest mental investment.
