“A coward dies a thousand times before his death, but the valiant taste of death but once. It seems to me most strange that men should fear, seeing that death, a necessary end, will come when it will come.” – William Shakespeare, Julius Caesar
“We suffer more often in imagination that in reality.” – Seneca
“I am an old man and have known a great many troubles, but most of them never happened.” – Mark Twain
The longer you procrastinate, the longer you suffer.
Do it now. Suffer once. If at all.
From my experience, the suffering from doing pales in comparison to the joy from completing.
