That’s understandable @erikzavodsky. The methods you find on the forum are luckily not mutually exclusive… you’ll need to do three things:
- create a memory palace to there the information somewhere
- create a number to image system to translate the information
- store the images for your number in your memory palace
To achieve your goal of 1,000 digits, you’ll need to create a memory palace with 200 locations. Consider this your canvas to paint on… without it don’t even bother getting started. One of the easiest ways is to use Google Street View (inside Google Maps) and choose locations that way.
If you go the pi route as @Erol suggests, you can start with 20 locations (5 digits each) in or around your apartment/house. After that move on to this post I’ve written previously on how to memorize the first 2,100 digits of pi (i.e., the 2,000 after your initial 100):
If you’re just getting started it’d be easiest to go with a 00 … 99 Person-Action-Object (PAO) system. The 3-digit system I mention in the post will require 1,000 instead of 100 images for PAO and even though it’s nicer to ensure image uniqueness, it’ll be quite a challenge for a newcomer to set it up… you don’t go running a marathon on your first day either.
So, find 20 locations somewhere to get started, then create PAO images for the numbers as you need them. Your choice if you use Dominic System or Major System to translate the digits into letter, but stick to one once you’ve decided (…personally, I use a 3-digit major system):
14 - TR TeRi Hatcher (person) doing something (action) to something (object)
15 - TL TyLer Durden (person) punching (action) something (object)
92 - PN PeNN & Teller (person) pulling rabbit out of (action) a hat (object)
*using major system to translate digits into letters
and then store the compound image 14 (person) with 15 (action) with 92 (object) in the first location… so if you are going bedroom, bathroom, kitchen, etc… or whatever makes sense at your place. Teri Hatcher is punching a hat in your bedroom. Add some reasoning as to why she’s doing that and you’re good with the first six digits of pi. Move to the bathroom and place 265358 there, etc.
By doing them in order of pi rather than 00 … 99 you will see some immediate impact, so that’s good motivation. Also you won’t fall behind on the number of locations in your memory palace. I suggest you use Paris as described in the link above once you make it past the first 100 digits (20 locations). It is really convenient to have the district numbers to keep track of where you are.
Also check out the link to Memrise in the post. Memrise is a spaced repetition software (SRS), which is a good technique to ensure that you don’t forget what you’ve memorized. Lastly, if it helps you with goal setting have a look here and consider getting on the list yourself. Might be additional motivation to keep that goal in mind:

Last bit of motivation… your goal of 1,000 digits was actually the world record in 1973. 
NB: for more detail check posts on the forum as far as memory palaces and major system (or Dominic System if you prefer those codes). You can skip number shape as that is single digit as well as linking method because 1,000 digits is too long to link and you’ll need to use a memory palace.
