Its a good idea to get in the habit of really listening to your inner voice once in a while and then tell it to SHUT UP!!!  When our brains are full of subconscious thoughts and reminders, they start to compete with each other to be heard.  Unfortunately, nagging and negative thoughts usually speak louder and are more persistent than your positive or constructive inner voice.  That negativity is bound to conjure up some stress and worry and even interfere with what really needs to be done.  When you do start to hear that inner nag that is judgemental or negative, remind that voice that you know what you're doing and tell it to take a break.  There's a good chance you'll hear a "thank you" from your positive, supportive inner voice.
