The best prepping tip I have is to start with the basics:
1 - Work out what you are prepping for. Write out a list of the top 10 most likely SHTF scenarios and work out contingency plans for each of them, then work out backup plans for those... odds are you'll need another set of backups after that
2 - Work out a backup location that you can reach within a 24-36 hour timeframe. Katrina, Haiti, the Christchurch quakes and the Brisbane floods all showed a 1 - 2 day gap before the criminals were out looting etc. If your safe location is further out, do a test run of getting to it without using roads, make caches where you need to or plant some edible plants (the more unrecognizable the better) along the route. Depending on your backup plans, you may need a couple of BoL's.
3 - Blend in. You don't want your house to be the flashest or the most untidy, either could make you a target. If some house are already boarded up/abandoned, make sure you have enough materials at hand to make yours look similar.
4 - Start becoming as self sufficent as possible. Even if nothing ever goes down (as unlikely as it seems), you can never go to far wrong if you can produce your own food and power.
5 - Stockpile knowledge, in as many mediums as possible. You may never require it, but one day your grandchildren might.
A couple of notes re the Home Defense tips.
If you get into a knife fight with an intruder, you are likely to get cut. If you can get your mind used to this, you have a lesser chance of freezing when it happens.
use a slashing technique not thrusts ( if you don't get it right your weapon might get stuck in/on a bone) and at the throat, eye's and gut - these vital areas tend to make opponents recoil.
Keep a handful of ballbearings close to the bed. Thrown they can cause a lot of damage, thrown on the floor they can unbalance an attacker.
If you plan on confronting a home intruder - pick the area where you want to do it and configure it to your advantage (furniture on rollers/ many small hard objects/ bulky items that can be used as a shield etc).
