I have an intelligent mind. My problem is that I sometimes want to compare what is going on in my brain to the stuff of the world. I check out by going zombie on the internet or television and lose site of what is really important to my happiness. There is absolutely nothing wrong with small doses of that unless the "stuff of the world" becomes a substitute for my own neurological exertion...or in the case of meditation....non-exertion.
You can do a search on meditation and get hundreds of ideas on how to go about it. The common thread is that mindfulness is an effective way to help you become quiet enough to become aware of who you are in the world by ignoring it. I set the timer on my oh-so-worldly iPhone and sit for 5-20 minutes and breathe...get distracted...and breathe again. The amount of time is not as important as the intent. If I set aside to time to focus on an activity, eventually my mind AND my body adjust to affects. I relax. I feel the presence of my Higher Self. I listen. And....I trust my own decisions. The nice thing about trusting myself is that I begin to move forward with the things that matter to me. It removes the stickiness of self-doubt. Centering...the thing that is meant to still my activity...actually begins to elevate the effectiveness of all that I do.
For an investment of 5-20 minutes a day, that is a big payoff!
