Just cashed out for 2M. What now?
nazgulnarsil: a lot of people are talking about "taking time off to think" but not really being more specific than that.  This is not just a vacation, this is a vitally important step.  Assuming you can make 3-5% off the 2M you are set for life.
Now comes something that few people have ever been able to do: actually decide (with a huge degree of freedom) what your time on this earth means to you.  
It may sound silly now, but you have just been reborn.  You are no longer subject to the same rules of life that most are.  You are literally a different person, though you may not know it yet.  Take things slow, like a baby taking first steps.
And don't think that this all involves naval gazing.  Look at the other people in your life and what their relationships means to you.  They have to start all over with a new You as well.  It can be rough on people.Not taking this seriously is the prime reason new wealth often loses it.  Everything else is details.
