How do you decide?

I truly am asking this in a hypothetical, but not rhetorical manner.  We are not contemplating any major life changing decisions right now. . . unless you count what color the downstairs bathroom should be and how on earth to teach our son to not whine for everything. . . .

How do you make the big decisions in your life?  The ones like. . .

. . .what career should I choose,
. . .should I switch careers,
. . .should we have kids,
. . .should we have more kids,
. . .should we buy this house or that house,
. . .should we move to this city or stay where we are at,
. . .do I stay home with the kids or go back to working outside the home? . . .
. . .and all the others that I can't think of but I am sure we all encounter throughout life.

Do you pray, seek counsel from friends, family, go with your gut?  Does it take you months or days. . . or hours to decide?  Do you find you and your spouse (if you have one) typically agree or is there usually a compromise?  Do you feel good after making a big decision or do you have 'buyers remorse'?

I am curious. . . . and I love to hear from you . . . . . . . . .all 4 of you ;)!
