The skills you need to succeed in this economy you often cannot learn from books.
The two skills I need to be marketable:
- WooCommerce (an e-commerce plugin for WordPress website) product listing and single product page customization.
- Responsive Web Design
There are a few books on the latter but the former can only be learned by googling around and even then the information is very arcane and sparse.
Everyone crows about how “education” will solve our problems. It won’t because a lot of what you learn is obsolete in the span of a year or two. This is more true in programming than other disciplines but as more and more fields gets technologized one’s knowledge becomes more ephemeral.
