The skills required for most effectively displaying
information are not intuitive and rely largely on
principles that must be learned.

How to learn and where from?
Practice, practice, practice – experience is the key
Seek potential projects – paid, curiosity, contests
Learn about yourself – take notes, self critique
Technical skills – push yourself out of comfort zone
Evaluate others – silently or provide reviews
Publish yourself – encourage and digest peer critique
Craft
Online content – immerse yourself in the community
Books – so many invaluable references and inspirations
Academia – papers, journals
Conferences – within the field and around it
Training/education – look for good training provider…
