10. Best Practices: Comment your code, use meaningful variable names, and keep your procedures short and focused on a single task.

Example: Imagine you want to create a macro that highlights all cells in a column that are greater than a certain value. Here's a simple VBA code snippet that accomplishes this:

```vba

Sub HighlightCells()

Dim cell As Range

For Each cell In Range("B1:B10")

If cell.Value > 10 Then

Cell.Interior.Color = RGB(255, 255, 0) ' Yellow color

End If

Next cell

End Sub

This code loops through each cell in the range B1 to B10 and if the cell's value is greater than 10, it changes the cell's background color to yellow. It's a basic example, but it illustrates how you can use a loop, a conditional statement, and interact with cell properties to automate a task.

Understanding VBA code is a journey of discovery, where each new concept learned can significantly enhance your ability to automate and customize Excel tasks.
