Here comes lots of random pieces of advice...

Ain't no shortcuts.

Be prepared, becoming a good programmer (there are lots of shitty programmers, not so many good ones) takes lots of pain, frustration, and failure. It's going to suck for awhile. There will be false starts. At some point you will question whether you are cut out for it or not. Embrace the struggle -- if you aren't failing, you aren't learning.

Remember that in 2021 being a programmer is just as much (maybe even moreso) about picking up new things on the fly as it is about your crystalized knowledge. I don't want someone who has all the core features of some language memorized, I want someone who can learn new things quickly. Everything is open book all the time. I have to look up pretty basic stuff all the time, it's just that it takes me like twelve seconds to look it up and digest it.

Build, build, build, build, build. At least while you are learning, you should always be working on a project. Don't worry about how big the project is, small is fine.

Remember that programming is a tool, not the end goal in and of itself. Nobody gives a shit how good a carpenter is at using some specialized saw, they care about what the carpenter can build with that specialized saw.

Plan your build. This is a VERY important part of the process that newer devs/programmers like to skip. You are always free to change the plan, but you should have a plan going on. Don't store your plan in your head. If you plan exists only in your head you are doing it wrong. Write that shit down! If you create a solid development process, the cognitive overhead for any project goes way down.

Don't fall into the trap of comparing yourself to others, especially to the experts you are learning from. They are good because they have done the thing that you are struggling with at least a thousand times.

Don't fall into the trap of comparing yourself today to yourself yesterday. This will make it seem like you haven't learned anything and aren't on the move. Compare yourself to yourself last week, last month, last year.

Have experienced programmers review your code. Don't be afraid to ask, most of us really really enjoy this (if it makes you feel any better about the "inconvenience", it will take a mid-level waaaaay less time to review your code that it took for you to write it, and a senior dev even less time than that). You will hate it, it will suck having someone seem like they are just ripping your code apart, but it will make you so much better so much faster than just relying on your own internal knowledge.

When you start to be able to put the pieces together, stay humble. I've seen countless devs with a year of experience start to get a big head and talk like they know shit. Don't keep your mouth closed, but as a newer dev if you are talking noise instead of asking questions there is no way I will think you are ready to have the Jr./Associate/Whatever removed from your title.

Don't ever. Ever. Ever. Criticize someone else's preferred tools. Tooling is so far down the list of what makes a good programmer. This is another thing newer devs have a tendency to do, thinking that their tool chain is the only way to do it. Definitely recommend to people alternatives to check out. A senior dev using Notepad++, a terminal window, and a compiler from 1977 is probably better than you are with the newest shiniest IDE.

Don't be a dick about terminology/vocabulary. Different words mean different things to different people in different organizations. If what you call GNU/Linux somebody else just calls Linux, let it go man! You understand what they mean, and if you don't it's your job to figure out what they mean, not tell them the right way to say it.

One analogy I like to make is that becoming a programmer is a lot like becoming a chef. You don't become a chef by following recipes (i.e. just following tutorials and walk-throughs). You become a chef by learning about different ingredients, learning about different cooking techniques, learning about different styles of cuisine, and (this is the important part), learning how to put together ingredients, techniques, and cuisines in ways that no one has ever showed you about before.
