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…
