If you can't invest in a studie it also helps a lot to skip searching how to do things in a specific language. You are much better off by searching for solutions. For example: 'how to create modular programs' will give you more valuable results than 'how to create a website in PHP'. Things like dependency injection work the same in most languages so it's more helpfull to understand what it solves than how to solve it in language [x]
