People can change their lives by altering their attitudes of mind . There are small differences between people , but they produce a big difference . Little difference is attitude . The big difference is whether it is positive or negative . Our attitude is the passport to a better tomorrow . Thinking , speaking and acting with excitement you will attract positive results. It is true that thought precedes action . Even if you think and talk positively , you will not fulfill your dreams until you act . Think of your attitude is a mental filter through which we perceive the world . Some people have a filter optimistic and see the glass half full , others have a negative filter and see the glass half empty .
