Some people believe that holding on and hanging in there are signs of great strength. However, there are times when it takes much more strength to know when to let go — and then do it.

The quotation reframes “strength” as discernment rather than endurance. It challenges the common moral prestige given to persistence—staying in a job, relationship, belief, or conflict simply because quitting looks like weakness. Instead, it argues that real fortitude may lie in recognizing when continued attachment is harmful, futile, or self-erasing, and then acting on that recognition. The second clause (“and then do it”) emphasizes that insight alone is insufficient; letting go requires a difficult follow-through against habit, fear, guilt, or social pressure. In this sense, the line functions as practical counsel about boundaries, self-respect, and the courage to accept change or loss.
