A dialog from Nadine Gordimer’s novel, A Guest of Honour (page 222):

‘Why does playing safe always seem to turn out to be so dangerous?’
‘It’s unlucky . . .
. . . because you’re too scared to take a chance.’
‘It’s unlucky to lack courage?’
‘That’s it.  You have to go ahead into what’s coming, trust to luck.  Because if you play safe you don’t have any, anyway.’
‘It’s forfeited?’
‘Yes.’
