Just do good, develop good habits, focus on what you wanna do and do that and forget about stopping the bad habits. Eventually you will find yourself a better person with those good habits you wanna possess. Like ቆሻሻ ውሃ የተሞላን ብርጭቆ ፡ በመድፋት ፈንታ ዝም ብለን ንፁህ ውሃ ብንጨምርበት መጨረሻ ላይ ብርጭቆው ውስጥ የምናገኘው ንፁሁን ብቻ ይሆናል። And follow the replacing principle. Feed your mind with those good thoughts coz ባዶ መሬት አረም ማብቀሉ አይቀርም።
