Most people do end up specializing but since you feel that you can't at the moment the best way is to understand the underlying concepts. One thing I've found helpful is to keep example applications and work you've done locally on your computer. I keep mine sprayed by project type ie wordpress, joomla, angular. It's helpful to start building generic utility libraries that are usable across projects. The key point is to be able to reuse techniques, code patterns and hopefully code across multiple projects. I've also seen friends blog what they've learned so that they can quickly relearn what you need
