Hi.. I don't writing but I maybe give you some idea for writing. You say focus on what important, is writing not important?
Juan - If you making it important then you should set a time for it. Maybe 30 mins to hour. If you havening kids or husband, you tell them you are writing, then lock you self in a room where you can writing. I sure they can doing without you for that small amounts of time. You donts havening to spend hours to writing. Short amount of time you can accomplish many.
Tou - Finish what you start to write. You can writing many things but if you donut finishing it, it not good.
Tree - Carry a note pad. A small mini note pads. Ideas don't only comes when you sitting down to writing. They can come anytimes; when you dropping kids in the pool, driving on the freeway, or just trying to ignore a chinese coworkers conversation with you. That what the notepads for.. writing down you ideas otherwise you gonna forgetting later.
Floor - write of perish.. so just do it.
