Does positive thinking helps in making a person self developed ?
Weakness of attitude becomes weakness of character. Albert Einstein, 1879-1955, German-born American Physicist
So be positive. In life there are two types of people.
First are those who are nice, good-hearted, & compassionate but can't make much happen.
Other kind can make everything happen -- they're the creators, the go-getters, and the aggressive producers in society. However, they're often self-centered, greedy, and unethical.
Wouldn't it be great if you could make things happen in a really big way but not lose your integrity?
HOW ? - INSTEAD of just being negative learn:
* How to always be satisfied and motivated regardless of your circumstances
* Why all people have freedom but very few have liberty
* What competing commitments are and how they prevent you from having what you want in life
* The secret to operating optimally in an untrustworthy environment
But positive thinking also involves taking risks, but calculated risks, and it does not mean recklessness in attitude either.
In a nutshell, if one does not think that there is something good that will come out of a thought both for him/her as well as those whom he/she is dealing with, he/she would be a negative thinker and wont go too far in self development.
