If you watch your thoughts over a full day, which by the way I recommend highly, see if you can count the number of times your mind drifts automatically toward observing, evaluating, and/or criticizing someone else's behavior. If we're really honest with ourselves, it happens many times everyday. Why? Because it's the default habit of the ego to deflect away from itself and focus on someone else. In other words, we'd rather think about someone else's stuff than our own. It's sort of a built in protective mechanism. It's a way to see and confirm who we are in a positive light.
Ignorance is Not Bliss
This may seem like an odd question to ask as many people believe personal history is very important. On the other hand, others say we should strictly focus on the present and not be dragged down by our histories. I think both viewpoints have some validity for different reasons. There is a middle ground which both makes use of personal history while keeping a strong foothold in the present and interest in moving forward. I believe this middle ground is by far the most productive approach and this is why: every present moment contains all that's come before it in the past, and also holds the seeds to the future. Time is a continuum. And where we are at every moment is tied to where we were and where we are going. The only way this does not apply is if you are speaking on a very metaphysical plane that is beyond time, but for our purposes here, we are working within time.
If you've ever read any success literature or listened to CD programs about how to be successful or how to reach your goals, then you are very likely familiar with the current focus on "practicing gratitude." There are many ways to accomplish this including such things as keeping a gratitude journal, writing little notes of gratitude directly to people you want to thank for something, putting up reminders on the wall where you work or in your home that say something about gratitude, posting words of thanks on social media, and so on. There is no one correct method. The idea is to pick something that works for you and do it. There are, however, some qualifications that can make the practice more effective which I'll list here.
The Problem with Exaggeration
You probably know what I'm going to say from reading the title before I even begin. I say that because I think we're all familiar with using the words "always" and "never" to describe something, and especially when we are describing someone else's behavior. "You always leave your clothes on the floor in your room." "You never admit that you're wrong. NEVER!" "She always dresses impeccably." "He never eats meat."
