Where to start?

Here is a list of things I have been thinking about writing but not writing:

First, a trek to Aspen with my four-years' dead dog Pigeon's cremated ashes to drop in our fave spot up Hunter Creek, where we used to swim and hike 12 years ago;

Trying to manifest a 70's Mercedes SL for my trip to LA;

But manifesting a rusted out '71 380CD instead.

Trying to de-manifest said Merc;

Starting my second [unfinished] novel to avoid rewriting my sitcom for the US market;

The pleasure of reading Malraux's Anti-memoirs aloud to myself [I'm not as pompous as that makes me sound, I'm just weird]
