A random checklist

In no particular order, here are things to remember:

Front-end

• Always load images, gifs, videos etc. asynchronously
• Notification if JavaScript is disabled
• Only load data necessary to display contents
• Obvious, consistent navigation, links and headings
• Bigger text, less text
• Links to more complete information (e.g. read more)
• Printer friendly pages (CSS)
• Build code that is independant of interface

Team

• It's better to work together
• Don't underestimate your peers
• Don't assume people are dumb
• Not everybody needs to know everything
• Not everyone's job is equally "difficult" - that does not mean the "easy" jobs are less important! Everything has its place

Random

• Learn to laugh about your failures and mistakes
• Rub your ears outward till warm & red, this increases hearing instantly and increases concentration
• Drink a glass of water to help concentrate (brings oxygen to the brain)
