When you value your integrity at the highest level, living alignment with your word and following through with your commitments no matter what, there are no limits to what you can create for your life. However, when you make excuses, justify doing what easiest, and choose the path of least resistance, you will live a life of mediocrity, frustration and regret. Live with integrity as if your life depended on it, because it does.
As a leader, parent, or friend - don't let someone's poor attitude and poor performance hinder your commitment to holding them to higher standards. You don't need to make the person 'wrong' for the way they're behaving, simply point out that the behavior is ineffective.
If you don't make the commitment today to start becoming the person you need to be to create the extraordinary life you really want, what makes you think that tomorrow - or next week, or next month, or next year - is going to be any different? They won't. And that's why you must draw your line in the sand TODAY.
