Buy all the most expensive stuff right away. Then there is nothing more to buy.

cameras are like bike sin that you really can commercially obtain exactly the same stuff the pros use right off the internet or at any store. So buy the 1Dx, the 70-200, 24-70, and 100-400 L lenses .... and get the $15,000 Emonda with all the best accessories.

The if you are slow and take lame pics you can't blame the gear.

Whatever. With cameras I eventually got a hold of myself and decided i wouldn't buy another whatever until the one i had was really holding me back. i have a long lost of stuff i want ... and can kind of afford ... but I have to admit, my pictures won't be appreciably better just because I have the better gear.

Pretty much the same with bikes. I have bikes the capacity of which exceeds my ability. I could buy an "X" type of bike, but I wouldn't be faster/ride farther/ ride better/ have more fun because of it.

I talked my wife into expanding my stable (it's my money but it's also my headache if she objected) so I could go out today and buy another bike. Thing is, I already can't ride all the bikes I have as much as I'd like? A new bike would just be another bike on the rack.

And no matter how many bikes I have hanging there, I still have the same fat belly, weak heart, weak legs, and asthmatic lungs.

Equally I could get the 7DII I have been wanting ... and a better super-zoom. Thing is, my shaky hands will still be shaky, and my artistic sense will still be atrophied.

I have come to the grim realization that I have bought all the quality money can buy. No point is buying more stuff ... I won't be getting any better unless i make better use of the stuff I already have.

I guess the question I had to ask, was ... Will it make me better? Is it holding me back?

Like @memebag ; says ... when you can beat the rest on your rebuilt $300 yard-sale rescue bike, you will deserve a new bike ... but you might not even want one by then.
