10 year rules

 In your twenties work for someone or work for lots of people and gain knowledge, in your thirties work for yourself, become an entrepreneur, in your forties try and put this knowledge of 2 decades into your  work  and work with people whom you like and work on things which you like and which really matters to you and bring value to the table, in your fifties work with youngsters and policy makers and share knowledge and try put your perspective to make a small difference, in your sixties start a foundation work on the subject which is close to your heart and start giving it back, in your seventies relax and pen your thoughts and brush your memories, in your eighties say good bye and leave the world hopefully in a better place than you found, so that you can leave peacefully assuring yourself that you have contributed something rather than only consuming the offers of mother earth...
