Pride is self-importance and self-focus -- which leads to selfishness which is selfish thinking and selfish acting -- which is the opposite of Jesus' command of agape love (John 13:34).
Mowing Direction. Finally, you should mow your lawn in different directions each week so it does not lay down one particular way. If you mow the exact same direction every week, your grass will be trained to lay one way (much like training your hair to lay over) and this will cause issues.
However do not fertilize immediately right after mowing. OK to mow in the morning, but wait at least until the evening to fertilize. Reason is when cut the ends of the grass blades need to dry, or scab over so to speak. The dust from the fertilizer can stick to the wet ends of fresh cut grass and burn the tips.
