The thing about overreactions is that they are only overreactions… in hindsight.
But in some cases, if the action taken is not an “overreaction” then when the time comes to “overreact” it’s too late and at this point even an “overreaction” loses its potential impact.
So how do we overreact now? It takes guts to do so and face the inevitable criticism if the overreaction was uncalled for.
But if the overreaction was necessary, then you made the hard decision and did the right thing.
