As the title says really. I just watched an hour long programme on the SAS, was a great watch, actually, just about selection and training, you can watch that here if interested. I never had any desires to become a part of the SAS but after watching the programme, I'm sat here in self pity wishing I never threw away my dream of becoming a Royal Marine, I've been kicking myself for that for the last 3 years for it. That's the worst thing I've done and will always regret not retrying to get in. The best thing I've done though, is trade my dream of being a RM for my fiance, a degree and a tonne of debt lol how fucked up is that!? Anything you deeply regret? Also state the best thing that's ever happened to you (excluding kids and grandkids because that's an obvious winner ) so we can maintain a level of positivity.
