The gift of creative reading, like all natural gifts, must be nourished or it will atrophy. And you nourish it, in much the same way you nourish the gift of writing - you read, think, talk, look, listen, hate, fear, love, weep - and bring all of your life like a sieve to what you read. That which is not worthy of your gift will quickly pass through, but the gold remains.
