If you have free time, it is good to sit. If you don't have free time, then just do action Zen. But be very careful about wanting enlightenment. This is a bad Zen sickness. When you keep a clear mind, the whole universe is you, you are the universe. So you have already attained enlightenment. Wanting enlightenment is only thinking. It is something extra, like painting legs on the picture of a snake. Already the snake is complete as it is. Already the truth is right before your eyes.
