X2 on what Dave said about NO distractions. Some other good points above. :

Your FIRST priority must be SAFETY. Reloading is not difficult, but can have disastrous results if not done properly.

Only ONE powder canister for the cartridge you are loading on the bench. Keep powder in a separate cabinet and only get out what you need. I pour powder into the dispenser and place the can next to the dispenser.

Create a procedure for loading and follow it, EVERY TIME.

Do NOT start loading until you have read a guide and understand how to do it SAFELY.

If you aren't sure about how to do something, ASK

You AIN'T gonna save money. 😀 Biggest myth about reloading.
