My process is for those who cannot attain to my philosophy.

I break for the weak the chain of memory which holds them to the past; but stronger souls are independent of me.
They can unloose the iron links and free themselves.

Would that more had the needful wisdom and strength thus serenely to put their past behind them, leaving the dead to bury their dead, and go blithely forward, taking each new day as a life by itself, and reckoning themselves daily new-born, even as verily they are! Physically, mentally, indeed, the present must be for ever the outgrowth of the past, conform to its conditions, bear its burdens; but moral responsibility for the past the present has none, and by the very definition of the words can have none.
There is no need to tell people that they ought to regret and grieve over the errors of the past.

They can't help doing that.

I myself suffer at times pretty sharply from twinges of the rheumatism which I owe to youthful dissipation.
