A person can standout in a particular field because of his own abilities and strengths.
It will not be good to take advantage of other people's weakness. It is not a good idea to depend on other's weakness.
On the other hand the weakness of others is only an illusion where we temporarily appear superior or in advantageous position with respect to them. So that is not a thing to be proud of. Individual strengths are something to be adored in life for ever.
Knowledge is power.
In life we need to be dependent on our strengths and abilities to live our life, preying on the weakness of others and using it to our advantage is the rule in the jungle but not in human life. It would be immoral or demeaning to prey on the weak for our survival. Many of us would have given a bribe at sometime or the other for our work to be done but we never hold such people (who accept bribes) in high esteem.
