Slide 12

Would you truly be happy working in this environment eight
hours a day? This is especially important for choosing a
programming language.
Happiness has a cascading effect. Happy programmers do the
right thing. They write simple, readable code. They take
clean, expressive, readable, elegant approaches. They
have fun.
In summary, your team needs to work with tools they love.
Choose the fuse that gets people excited. You’ll generate
excitement and motivation and a better product as a result.
