It’s never to late to change your life & lean new skills.

I am 66 years old and have continued to update and lean new skills all my life,
5 year ago I was an IT Manager, then I was made redundant, at the same time my wife was diagnosed with breast cancer, so I decide to stay at home and help my wife through the treatment.
At the same time I taught my self some new skills, PHP, HTML, CSS and javascript, and started a website project.
My wife is now in remission, I am a freelance web developer, (part time) mostly working on my own projects.

I hope to have a productive life for at least another 20 years.
So sit back and say to yourself what do I really want t do, then make a plan and do it, you have plenty of time.
