Takes far less energy to always speak as honestly as you can.
when you don't you have to keep tabs on who you were untruthful with, about what, when. And they tend to snowball into making up more and more stuff seeking to save face. Then you might actually start believing the stories you've been telling. before you know it you are lost and it truly is a long path to find your way back to where the story all started. How many apologies to how many people will have to be made. How much courage will you now have to have to rectify the damage your stories have caused.
