Don't use the hardships of your past as excuses to deny the possibilities of your future.
Success is created through the performance of a few small daily disciplines that stack up over time to produce achievements far beyond anything you could of ever planned for. Failure, on the other hand, is just as easy to slip into. Failure's is nothing more than the inevitable outcome of a few small acts of daily neglect performed consistently over time so that they take you past the point of no return.
Every second you spend thinking about what you don't want in your life is a second denying focus and energy from getting what you do want. Every minute you worry about what's not working is a minute drawn away from creating what will work. And every hour spent reflecting on the disappointments of the past is an hour stolen from seeing the possibilities that your future holds.
Every second you dwell on the past you steal from your future. Every minute you spend focusing on your problems you take away from finding your solutions.
Your current conditions are echoes of your past choices.
