Dave Pelzer said this quote

Its all a matter of weeding out the bad and cultivating more productive thoughts. And just like pulling weeds, you have to get to the root otherwise that weed, the self-doubt, that negative programming, will spring back up and shoke off the flower that can blossom for you in the future.Be consistent. Apply that weed off whenever you feel the need. Every day see the brighter side of things. Continually tell yourself how lucky you are, how good your life is right now, and how things can only get better
