I am all about finding the fastest way to get from one place to the next. The thing to remember is that the fastest way to get from point A to point B is always a straight line. Don't believe me? Here's a math lesson that proves the point. Looking at the drawing above (distances in miles), if I want to get from A to B then there are two possible paths that I can take.
Path 1: You go to the right 3 miles and then left (up) 4 miles. You've just traveled 7 miles (3 +4).
Path 2: You travel diagonally 5 miles.
So Path 2 is shorter than Path 1.
Path 2 is a direct path from A to B. That's the key. There are no twists or turns that add to the distance. The most direct and straightest path will be the shortest.
Now if you're in the park, this doesn't mean you should cut across and walk on the grass to get to where you need to go. Paths are there for a reason and protect the grass from trampling. But if you're walking on a beach, swimming in a lake or something similar, your best bet to get somewhere is the way that is most direct.
You Ought to Know: The shortest distance between two points is a straight line.
