Don't just plan to write - write. It is only by writing, not dreaming about it, that we develop our own style.
P. D. Jamesto look back on one's life is to experience the capriciousness of memory. ... the past is not static. It can be relived only in memory, and memory is a device for forgetting as well as remembering. It, too, is not immutable. It rediscovers, reinvents, reorganizes. Like a passage of prose it can be revised and repunctuated. To that extent, every autobiography is a work of fiction and every work of fiction an autobiography.
