I believe that, without any knowledge of Astro/Horoscope, we do have conscious and sub-conscious awareness of our positive and negative aspects.
I have this observations on my childhood (& also adult life) heroes -- They all shared great mass support and had a great mass-mentality knowledge -- Basically folks with very STRONG Shani resulting in very strong Shani mahadasha results. One either gains or looses (gives away) to masses in Shani mahadasha depending on their past-karma with masses (as reflected by Shani's strength in their horoscope).
Following have been my heroes since childhood in Chronological Order:
1. Amitabh Bachchan
2. Balasaheb Thackeray
3. Imran Khan
4. O. P. Nayyar
These folks have a very strong/well placed Shani in their horoscopes.
Bachchan: Shani Mahadasha from 1969 to 1987
Balasaheb Thackeray: Shani mahadasha from 1980 to 1999
Imran Khan: Shani mahadasha from 1976 to 1995
O.P. Nayyar: Shani mahadasha fromo 1954 to 1973
These folks had mass-frenzies and mass-hysteria in their shani mahadasha. Tremendous mass-support in their Shani mahadasha. (They might have donated a lot of money, land and overall done service to masses in their previous births and hence the payback from the masses.)
Rather, their birth allowed those masses who were profited/benefited in earlier life to pay them back in respective shani mahadasha.
The points I want to make is :: You are always aware of your improvement areas and always find role models/heroes that have this style in abundance in them or their past karma! :)
My other 2 heroes Dilip Kumar and Sunil Gavaskar had a great Raahu/Rahu mahadasha in their peak times. Dilip Kumar from 1945 to Oct 63 and Sunil G from 1971 to 1989.
By the way both Sunil Gavaskar and MS Dhoni have Makar lagna and Mangal in 5th house in last 2 degrees of Vrushabh raashi in Mrug Nakshatra owned by Mangal. 2007, 2009 were very good years for Dhoni when current Guru aspected his horoscope Mangal. May 2010 to June 2011 will be great away from home for him and July 2012 to July 2013 will perhaps be the best year in his career when Guru will be in Vrushabh rashi.
