I would swear. In fact I am. How is that possible? /dies
Lots of beer! Never race sober
Just practice a lot, fly around and have fun. Stick near things, like stations or planet surfaces, so it's easy to judge your vector and how your controls affect movement.
A Sidey is perfect to start with, and your Hauler will be fine. Just expect a few rebuys as you start speeding up.
A good tutorial series to start with is here:

FAon is all about "point the ship and fly that way with main thrusters". FAoff is point anyway you like and fly with any thrusters you need. Vector is everything, and you can practice flying sideways, nose down, etc. as practice for this. Decouple your brain from the front of your ship and your primary thrusters.
Boost can also be your best friend, get outta jail free card. Boost into verts/lats for very rapid direction changes.
Of course, it can also be your worst enemy and kill you too...so work up to that!
If you want help/advice, Newton's Gambit's a discord/community of FA off pilots. We're here:

Lastly, I'll say again - have fun. If it's a drag, stop practicing and fly FA on a bit. Eventually you'll hate FAon cos it gimps your vertical & lateral thrust output.
