This is easily one of the biggest things I wish I knew when I started Mixing and Mastering.
Everyone is obsessed with fancy plugins and nice gear when they start out
However, there other things that are much more important and much cheaper that you need to think about first
When I started, I was on a Macbook pro like many other people who are starting out
That Mac did me good for awhile, but it certainly wasn't the powerhouse I needed it to be
That said, some small upgrades drastically improved my workflow, and they will improve yours too if you are confined to a laptop
Buy a cheap mouse, invest in a larger display, buy a USB bank, and thank me later
Having more screen real-estate and getting off that crappy track pad will completely change your life and speed up your workflow
I waited to do this, but once I did I could never go back.
Not only that, but a gaming chair, a nice table, blue light protective glasses, and a keyboard tray also changed my life
You are going to spend hundreds of hours sitting, and if you have a lousy chair you are going to pay for it.
I know I did...
I suffered from pain in my upper spine for awhile that made it impossible for me to work
I finally invested in a $120 gaming chair, and it changed my life
Also, having a big enough table to set my speakers where I needed them was a necessity
Another thing to think about is that you are going to be spending most of your career staring at a screen, and your eyes are going to pay for it if you don't protect them
I recommend that you buy some blue light protective glasses.
I was getting to a point where I couldn't stand looking at a screen anymore, so invested in some cheap $15 blue light protective glasses on Amazon and they made a huge difference.
I'm not sure if they were as good as Gunnar glasses, but they helped me out a lot, and they were cheap
Lastly, depending on your table and setup, a keyboard tray may be a huge help
For me, my table is a little too high, and my wrists were starting to kill me being on my computer all the time.
Getting a keyboard tray made a huge difference, and allowed me to lean back into my chair and position my wrists in a safer way, ultimately saving my back and preventing wrist problems
You may not be thinking about this stuff now, but you need to before it starts becoming a problem
