1) Some things that I have observed in @narendramodi's era.

He does not comment on everything.
He doesn't pick every battle.
He doesn't treat every setback as crushed ego.
He has shown enormous mental strength.

But the battles that he picks up, he usually finishes in style!

2) Even Narendra Modi's big supporters sometimes think he is "weak" because he did not win some battles. He usually fights battles after good analysis and on HIS terms. Hard for us to understand.

A tactic that he uses - Do not interrupt opponents when they are making mistakes.

3) I have seen Narendra Modi make his opponents self destruct.

His primary strength seems to be his ability to not get angry at his opponents. Once you are angry, you lose your analytical ability and become a mere troll (like you see some dynasty politicians today on Twitter).
