Hi Sypher,
Thanks for writing! Congratulations on your decision to put karmic management to the test. I started practicing this stuff around my 29th birthday as well, almost 10 years ago, and it's been the best thing that ever happened to me.
Some advice: be gentle with yourself. If you have deeply ingrained habits of procrastinating, embellishing, etc., it may be difficult to change them all overnight (unless, of course, you have the imprints for it to all work right away, which isn't out of the question). When making a big life change, I find it helpful to set small, manageable goals and then dedicate the result to being able to achieve greater goals.
For example, in the case of lying, you could set a small goal like "During my next phone call with my mom, I'm going to stop myself from fibbing at least one time." Then afterwards, say to yourself: "I dedicate this act of telling the truth toward developing a deep, unshakable habit of honesty." You may have to set a lot of small goals like this in order to retrain yourself, but the long-term result will be that your natural reaction in all situations will be to tell the truth.
In situations where I'm tempted to do the wrong thing, or I'm scared that something bad will happen if I do the right thing, I remind myself: "I can't get a bad result from a good deed." I've been amazed at how well this works, especially in the long run.
Please keep sharing your story!
Best wishes, and happy new year

Andrea
