My own time is passing fast enough without some national game to help it along.

Summary

The speaker does not feel the need for any mainstream cultural phenomenon, such as a national game, to further accelerate the passing of time. It implies a reluctance to participate in activities that might distract or make time feel even more fleeting, as the individual is already aware of the speed at which their own life is progressing.
