Admittedly stupid, I have inadvertently "hoarded" about 1.2MM Marriott points and 300,000 Starpoints over the last 10+ years. Each year, these programs devalue the worth of these programs significantly.

I currently travel at least one week in two for work, raise children and take care of a free standing house.

Generally I'm too tired/burned out to travel for fun on weekends owing to the business schedule and when the kids sports/activities call for travel, its rarely a hotel I can use the points and/or the group rate is so low it doesn't warrant burning points.
And when its time to take the kids away for a vacation / long weekend around their school schedules (i.e. Florida in March), there are no rewards to be had where I need to be.

I doubt these points will retain much value into retirement, which is at least 10-15 years away.

But it does show how the masses (including myself) get duped into thinking these are "real" currencies and make significant travel decisions / deviations based on maximizing miles/points with dubious future payoff.

I guess I am a hoarder by default & my circumstances. I'm sure others with different circumstances and greater flexibility see things much differently.
