VB.NET Developers: What’s Your Best Tip for Writing Cleaner Code?

I’ve been improving my VB.NET skills and would like to hear from others who use it regularly.

What’s one tip that helped you write cleaner, more maintainable VB.NET code?

Any common mistakes beginners should avoid?

Just looking for general discussion no services or promotions.

Not specifically for VB.NET and nothing new, but setting up proper version control early on (through Git) should be a must.
Also writing tests and commenting the code properly helps a ton.
I myself often started projects thinking they would only have a small codebase and didnt bother to setup Git / write comments only to do it all later on when I forgot how certain functions worked^^
