We learned from the Quran and Hadith that Allah gets very pleased when we leave all our wrongdoings, repent and revert to the straight path. But then we know It's the nature of man to make mistake, but we need to make it a habit to rectify our mistakes for then we become amongst the best.
The one who speaks a lot commits a lot of mistakes. The one who makes lots of mistakes commits lots of sins. The one who commits lots of sins will have the Hell-fire as the first place for him.
