Posting Etiquette
-
Ask the main part of your question in the title. This should be concise but informative.
-
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
-
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
-
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

Experience is the best teacher. Keep writing code, revisit old code and rewrite it.
Also, is worth knowing when not to optimise. Code you can read is code you can maintain, and some optimisations are not as readable.
Learn how to use a profiler. Its a bit of an artform, but learning to interpret the results will help you find slow code sections. It'll also help you determine if your optimisations are actually worthwhile. Measure first, optimise second.
This is one of my biggest pet peeves. So many people want to equate the number of lines as a sign of how well it's programmed. But all they really do is chain a bunch of stuff together that makes it harder to debug.
