I'm a horrible liar and a cheater, and I know that but I choose to keep on going.
Why do you lie and cheat?
Because I don't want to tell the truth or not do what I'm destined to do.
It sounds like you are aware of your issues. If you can't stop lying and cheating, you should try and get some professional help.
I can't stop now, it's way too late.
It may feel like it's too late if your lying and cheating has caused real harm to someone.  You won't be able to take back what has happened, but it is never too late to get the help that you need.  If you are truly trying to improve, then even the people you've hurt will forgive you eventually.
