great talkers are never great doers

Great talkers are not great doers. Few points for your reference are:

- It is one thing to promise big things and another to fulfil these promises

- This is an idea quite contrary to 'Simple living, high thinking.'

- Fantasies of materialistic superficiality never coincides with greet deeds and actions

- Oratory is a great power but is not fruitful without any action

- People who blow their own trumpet can hardly concentrate on their main task

- Great preaching and opinions do not hold any value unless they result in any success

Hope you will be able to elaborate on these!
