Five techniques

Five techniques are ways to do something better, faster, or more efficiently.
For example, if you want to make a sandwich, one technique might be to first spread the butter on one side of the bread, then add your fillings, then spread the other side of bread with butter, then put the two pieces of bread together. This is a technique that helps make the sandwich faster and more efficient.
Another technique for making a sandwich is to first spread the butter on both sides of the bread, then add the fillings, and then press the two pieces of bread together. This technique helps to make the sandwich stay together better.
These are just two examples of five techniques. There are many more techniques you can use to do almost anything better, faster, or more efficiently.
