Actually I wasn't. When I played the majority of my time was spent adjusting prices, not building or managing my transport network. Always got a constant stream of "Prices too low/high" messages that I was constantly having to change my prices. One minute the prices are dark green, the next it's dark red. Economy fluctuation is great, but it fluctuates too much and too often.
I simply ignore all "Ticket proces are too low" messages and only act on those messages that warn me on too high prices. As long as I earn enough money I don't care if prices are too low. That way I don't have to deal with ticket prices very often - only occasionally.
