If you're unwilling to adapt to the future, you'll justify the past. - James Clear

Men are born soft and supple; dead, they are stiff and hard. Plants are born tender and pliant; dead, they are brittle and dry. Thus whoever is stiff and inflexible is a disciple of death. Whoever is soft and yielding is a disciple of life. The hard and stiff will be broken. The soft and supple will prevail. — LAO TZU

Criticize to uplift, not to destroy.

Suffering drives progress.- The source of all suffering is the desire for a change in state. This is also the source of all progress. The desire to change your state is what powers you to take action.
With craving, we are dissatisfied but driven. Without craving, we are satisfied but lack ambition.
