I've gotten ahead in life from being a liar.
Are you sure? Why do you think lying has helped?
I find it easier to get ahead when I manipulate others.
It's understandable that you think manipulation is best since it has worked for you. However, you should be honest in your dealings with others to get what you want in life. If you keep manipulating others, it will catch up to you and you will find yourself alone when it does.
Haha. I'm way to smart to worry about that.
The saying goes "pride comes before the fall", so it feels like lying might be on your mind because you sense it could catch up with you. But even so, you should be honest not because you may get caught lying, but because you will have a clear conscience and it feels better to earn things honestly.
