This is an oddly weird thing to be dishonest about.
If anyone has an issue with me blocking some focus time to get things done, I'm happy for them to take it up with my boss, challenge my priorities and see what happens then.
She picks up my errors and laughs as English is her second language and my first. She has also noted that I use commas in strange places and don't use them when I should. My writing also contains too much repetition. For example I often will start several sentences the same way in a paragraph.
I should note, that the laughter is not discouraging, it's simply the way we interact.
The reason for asking was that I expect she knows you best, and she might give the most direct and tangible advice on what to improve.
I'd work on these aspects first, then move on to some suggestions in this thread.
Something that has worked for me is to keep a list of mistakes I made in the past, or improvements suggested to me. I use it as a form of checklist to go through before sending off a new document, to at least avoid mistakes I've made in the past.
I don't know my machine's specs: it doesn't really matter anything off-the-shelf from Circuit City or Best Buy is fast enough for what I do.
I have a windows desktop machine from 5 years ago that I run Visual Studio and dozens of embedded IDEs on.
All my networking / cloud dev is done on three different linux laptops (all Dells that were repurposed): Qubes, Ubuntu, and FreeBSD. (FreeBSD has a few other images on it with Grub including Win10.)
And then I have two macbook pros, an x86 and an M1 that I remote desktop/VNC to the other machines.
I prefer laptops because they take up less space and are portable.
By embedded I mean products based on Arm Cortex-M and -R, Renesas RZ/RL/RX, TI 430, Synopsys ARC, PIC, Atmel, etc...
