Windows 7 - What do you regret?

Granted, many of us don't cry over spilled milk, or have moved on and don't dwell on the past, but there's always something that we can think of that we regret.
I'll go first.

Letting a few good (marriage material) women get away.

Not buying that Samsung 830 64Gb SSD for $99.99, a few days ago.

Not having a better relationship with my siblings.

Getting rid of my Korg Extreme 61 key keyboard.

Getting rid of some great equipment because I didn't have the space.

I like most of your answers that are not related to computer equipment.
At age 62 I could have a big list but as you get older you get wiser and family, friends and health should always be in your present mindset.

When you start losing family and friends because of death reality sets in and you start thinking about using your valuable time in a more meaningful way.

Hope this is not too spiritual but your life and time on earth is too short.
Do the meaningful stuff now and not which you had when its too late.

Tell your family members how much you love them and don't be shy because tomorrow may not come.

My thoughts.

I wish I had caught the computer bug in 1973 when my 8th Grade class got to use a terminal for a week. I wrote a program to find prime numbers, thought it was pretty cool, then forgot all about it.

Fast Forward 22 years to 1995 and I bought the first computer I ever owned and was instantly hooked. Now I am 52 years old and finishing my college degree in IT. A lot of years in between running in circles.

Oh, and that girl in High School who had to stop by her office on the way home from a date when it was closed and we were the only ones there? I wish I had figured out why she was doing that before I took her home and kissed her goodnight on the front porch with her old man glowering at me through the window blinds.

To be honest, not much really. I only ever really regret things for a day or so and then get over it.
