I think the most common cause of lying is to COVER UP things we do not want exposed and avoid getting into trouble. Most people instinctively want to be trouble-free, so when something comes up that might get them in trouble, they can get pretty crafty with the lies.
This tendency can be changed by being more honest, upright, forthright and doing the right things. And: when you do mess up or make a mistake, instead of lying about it, fess up and deal with the consequences. Having to deal with the consequences of your own actions is a real game-changer for sure.
So, stay out of trouble, Jared, if that's one of your issues. Whenever you get into trouble, own up to your part of it, be honest with yourself first and honest with others. Let the cookie crumble over the TRUTH. And, remember the truth will always win even if it wins in ways we don't expect.
BTW: I give you credit for admitting you are a pathological liar.
Being honest and transparent isn't something that comes naturally for most people. But, if you want to live an honest life, it's totally possible.
