People say lots of different things, whether they mean it or not is a different issue entirely. Words are powerful and must be used carefully to maintain a certain level of peace and tranquility. However actions are much more powerful than words, especially when there are consequences. So it's important that our actions are founded on personal ingenuity.
When we say something, it's beautiful when our actions back it up. It cultivates trust amongst individuals and societies. The reason lots of people don't trust politicians is because they words and actions don't correlate. They speak very smoothly and gracefully but the final actions are questionable. The actions they perform eventually define their legacy and accomplishment.
The truth is whatever we decide to do per time is solely our choice. The resultant effect may impact several millions. So we must weigh our true intentions to bring forth our best actions every time. When our actions genuinely find expression we can have the loudest voice. This is how great people have made a big difference.
