"To the Chu Kingdom," came the reply.
"But the Chu Kingdom is to the south and you're heading north," he said. His friend smiled confidently, "No problems, my horse is very fast."
"But if you're on the wrong road, it doesn't matter how fast your horse is !"
His friend smiled and replied, "No worries, I have a lot of money-lots !"
"If the road is wrong what use is money ?"

You must always check your direction otherwise all your efforts will still be in vane, and you will never reach your destinations.
A full day of activities or a full schedule doesn't guarantee that you are already going towards your goals. Lots of resources that are used don't guarantee that you are going to succeed, they can be a lot waste of energy.
