I've never tried to block out the memories of the past, even though some are painful. I don't understand people who hide from their past. Everything you live through helps to make you the person you are now.
Before you speak, listen.
Before you write, think.
Before you spend, earn.
Before you invest, investigate.
Before you criticize, wait.
Before you pray, forgive.
Before you quit, try.
Before you retire, save.
Before you die, give.
The necessary thing is after all but this; solitude, great inner solitude. Going into oneself for hours meeting no one - this one must be able to attain.
