It is better to practice a little than talk a lot...

In general; people have the tendency to make empty promises. They talk a lot and don’t live up to their words. It is a shame because people judge you based on this fact. People say that they will do things that they end up not doing after all. Words come out easily from the mouth; the hard part is when you have to act regarding what you said….Hmmm; this is when people don’t remember that they promised something in the first place.

People should act more and talk less. It refers to the saying “Actions speak louder than words”. By acting you actually demonstrate that are trustworthy and reliable. When you live up to your word; people have a reason to trust you and therefore they can rely on you. We should practice it in our daily lives as it will permit to avoid any negative situations (lack of trust from someone else).
