I am reading This Thread with much interest, wondering what I might regret not doing when I get to 50 when I'm in my 40's.
Now I am considering my future self looking back on now. I am on the fast train to my 30's and so far feel like I've wasted a hell of a lot of time not fulfilling all the dreams I have had over the years.
I don't want that in my 40's. I'd hate to think "Oh buggeryfuck, here I am 10 years on and nothing has changed". I wan't to look back on my 30's and think "what a brilliant decade, how can I improve upon it?"
Tell me what you would tell your 30 year old self at 40+. Inspire me to get off my arse, pull my finger out, replace it with a rocket, hike up my socks up and actually DO something before I wither away.
