make a deal with yourself to go only where the facts lead, regardless of what your feelings are or how that impacts your current beliefs.
keep an open mind and dont stop researching. Allow (or even force) yourself to question everything.
Do some reading on critical thinking and logical fallacies so you can develop a working bullshit meter. Being a born in JW means most of us dont have one, so we are suckers for bullshit even after leaving the WTS, so develop a working one.
You wont go far wrong if you can do this.
