My dad and mum worked about 100 hours a week (self employed) from the month before I was born until I was 21, then they dropped down to 50 after that. So my Dad's first holiday since I was born was when I was 21. He had a two week gap and went to India with my mum, grandma and brother.
What did he do in his spare time when he had some? He spent it building his property portfolio. Now when he retires in just over 4 years, he'll be able to do anything he wants.
