@OgNasty - It would clearly be bad mistake selling at $140k when 7X that amount ($1 million) is just six or 7 years away in 2031/2032 - unless of course you don't expect to still be around then.
You must be very young. It's not about still being around. Go through a pair of cycles, add 10 or so to your age, and you might begin to understand some grown up talk.
