Everything is still possible

The past can be remembered or regretted, the future is full of possibility.

We cannot change the past; we can have regrets, remorse, memories. The future instead is uncertainty, desire, anxiety, open space, destiny, perhaps. We can live toward it, shape it, because it does not yet exist. Everything is still possible… Time is not a line with two equal directions: it is an arrow with different extremities.

— The Order of Time, Carlo Rovelli
