I find the follow approach quite useful.

1. First write down a bunch of idea of how I might tackle the problem - includes lists of stuff that I might need to find out.

2. Look at ways I break the task down to 'complete-able in a session'.

3. Implement, in a way the code is always 'working' at the end of session.

4. Always do a brain dump into a comment/readme at the end of the session - to make it easy to get going again.
