content: With age comes wisdom,  Not really true, I never became wise or mature. The reason is that in order bring projects to a success (developers world) you need passion. And passion cannot be controlled; let it free and thy will land your project safely.   I wish I had the money, because I'd start a company that exclusively hired people age 40 and up.  40+ do not guarantee that they are better than younger ones. Look at their history. The ones that still developed after decades are the ones you need to get. Not the ones that turned analyst or manager. Developers with 20+ years of experience develop in a different order than you will teach in schools. Trust them, even if you do not understand what they are doing. They will probably violate design patterns in the book but that is just because they are creating new design patterns that will work better for that kind of project. But an unexperienced manager will have his instincts screaming as hell because it is not what he was taught in school. So they will try to sabotage you and correct the oder people. I have noticed that 34 years of professional experience is the maximum as a developer. I estimate that ath 54 or 64 they have nearly the same experience because the PC world started 'professionally' around 1982. I only met one guy that was 54 and still a developer. But what was amazing that he had a very deep understanding of how software works, and had an instinct in knowing when a project is a success or failure the very first hour he look at the analysis. The thing that I learned from a good manager is that "Don''t tell older people what to do, they will rebel. Trust them that they will do it correctly and your project will succeed"
