There can be no ideal person but there can be ideal ideas. Only one thing that a writer needs is ideas. They may or may not be ideal.

Ideas get a Nobel Prize if written in the proper manner. 

Ideals can be persons , nations, situations, affairs, or situations but they keep on changing with time zones, places, persons and time of the judgment.   Some ideals are now no more ideal. 

Philosophies change. The more successful writers challenge the ideas and become ideal for that time period but if the system gets changed they may face trouble. People worship people but suddenly if the situation changes the ideals also change.

Man is not a polymorphic animal - sorry, not animal, but a highly evolved organism - yet his ideas are polymorphic.  They keep on changing depending on your profession. 

If you are in marketing for a company, your hair oil may be the best oil, but if you are an advertising agency, the best cement is the one your customer sells. 

If film actresses start taking baths with the soaps they advertise ( I don’t know the reality of it as its too personal to ask which soap do you use) but people sell their voice, their speech that is also an idea to make money. To make money by hook or crook is considered ideal in business but renunciation has been in vogue in good olden times. What has changed? Human society, need or greed for money?

Perhaps now human civilization is losing ideas of saving environment and want to live in present and utilize all resources at the fastest rate and they have no idea what is going to happen if nature is gone. There will be no life on this earth.

But where are those ideas and ideal people whom we can tell our children to follow?

Idol is made when one is more than ideal or is no more in this world but opinions may vary about the same person or idea in space of time and place.

What is your idea for today?

What an idea sir.
