On the ability to count to 3

On the Tele Discussion Page Reissue (TDPRI), there's a tread called "Post your three no-brainer tips you've learned here". This is my contribution:

1. You can do it. Learn a technique. Mod your guitar. Build the thing from timber and finish it. Wind the pickups. I haven't done much -- I've modded every superficial thing on my #1, leaving only the fundamentals like electronics, nut and fretwork left for me -- but for any given thing I want to try, I know that a) I can do it and b) someone on TDPRI will tell me how.
2. For hot country guitar, you need a compressor, a clean amp and rubber-band strings. And, of course, a Tele. Unless you want to do it some other way.
3. The most expensive guitar/amp/pedal/cable isn't necessarily the best sounding guitar/amp/pedal/cable. Specifically, the SX guitars from Rondo are perfectly good guitars that make great mod platforms and are even pretty good guitars out of the box.
4. The Parsons White isn't the only way to have a B-Bender. And you don't necessarily need to bend the B.

OK. Clearly, I have lost the ability to count to four. But that's my take. What 3 (or more, or less even) no-brainer tips do you have?
