I didn't enjoy being thirty at all - it felt like a real milestone. I didn;t care about being forty, and cared even less about being fifty.
At fifty-three, i can honestly say that I wish my career and personal life had gone other ways, but the choices i made were the right ones at the time - some by luck, some by judgement, and as Oscar Wilde said "The trouble with youth is it's wasted on the young."
I don;t regret, and I only look back at the good parts, and see my liffe as an education. I know i will never be the Johnny Depp that I envy so completely, but my ability to hold witty and insightful conversation is well above average, and i content myself with that.
I have a lovely wife, three wonderful duaghters, and two grandchildren, all well and healthy. I have a job, a hobby that pays money, no serious physical defects, and I often feel I am seriously lucky with how my life has turned out.
You will look back on this time, and put it in perspective - so why not try a bit of that now?
Be happy.
