Think about it.
If a person at 70 says that they want to be rich, President of the US, Pres. of a major corporation, an engineer, a doctor...
it CRUCIALLY depends upon what they already have accomplished.
If they have no STEM training, and were not good at math or science in school, the time necessary to acquire the background to even *begin* to work on an engineering degree is a big obstacle. The person would need remedial math and some science would help, then they need calculus (three terms; this depends upon algebra, geometry, and trigonometry), and ordinary differential equations (one term; this depends upon calculus and algebra and imaginary/complex numbers)...a year of engineering physics with a lab...a huge list of requirements for engineering (depth in your field, breadth across engineering, so many units of math & science, so many units of analysis and synthesis)...BESIDES fulfilling the institution's requirements for an undergraduate degree.
That time alone could mean you won't be able to make it.
Similarly for medicine, a business education.
If "rich" means "billionaire in US dollars" where you *are* at 70 *financially* also has a bearing on it.
Politics...starting at 70 can be done, but again it is hugely dependent on where you are in terms of your knowledge, etc.
Can your outlook help you? Yes.
Can it guarantee the specific results you seek? No way.
And to say
You don't have to WORK hard, but you need to THINK hard.
LOL If you believe that you can become an engineer without hard work, please do so. Sounds like he's another salesman of the "law of attraction"...not gravitational or electrical...but...yeah.
I'm sure his "proof" is not an actual proof.
