A. Poor grammar.
A. Walking. Which is almost the same as writing: you look busy.
A. Yes. Poetry: Galway Kinnell, Gerald Stern, WS Merwin, Robert Hass, Zbigniew Herbert, Joseph Brodsky, Derek Walcott, Larry Levis. Rumi. Poetry is magic: the right poem always finds you. The same goes for much of Jorge Luis Borges's writing, I think.
A. Love language. Take in the world with your heart open. Break rules. Don't limit yourself to one sentence if you must say more.
