Make it up!

Individual traits and circumstances have to be taken into account. Making it up is not winging it.  It’s being innovative.

So take a look at the tried and tested methods.  See what has worked for other people.  But really keep your eyes open, don’t just follow the steps.  Think about what aspects you can take and build upon for yourself.  And if there isn’t anything plausible out there, make it up.

Or someone else will.
