Hi guys, I'm glad this thread has been useful to you. I sometimes find myself thinking about how to improve it.
I added some points to existing points, highlighted in blue below:
2. Money can buy you 'better' guitars in terms of quality of build, materials, component parts, craftsmanship, etc. (although better parts and materials does not necessarily ensure better tone). If you can't afford 'better' gear, tough luck, just deal with it. [Note: Money is also a function of time. If you're smart with your gear money and saved up for long enough, you can buy what you thought only the rich guys could buy. It takes discipline but it's possible.]. On the other hand, guitars sound like guitars. Improvements in guitar making/manufacturing technology, accessibility of that technology, and the law of diminishing returns ensures that decent quality guitars are more affordable and can take the issue of money off the table very quickly.
11. Don't let your ego or someone else's get in the way of your enjoying guitar on your own terms, not on someone else's. If you need someone else's -- whether other forumite's or top builder/gear expert's -- validation to enjoy your gear, you'll never be content and happy. Remember that the primary aim of good gear and tone is to inspire YOU and make you play and sound good. The audience and any other person is just secondary.
Hope this is useful.
