It sounds like you have all the tools to still make money, but you just don't want to put in effort for what you perceive as lesser gains (after having cashed in by hitting the early market).

Go play something else if you're not having fun. If you're so well geared, capping your myth shouldn't be an agonizing endeavor.

Otherwise just count yourself lucky that you were able to cash in while the market was good and actually have a stack of gil.
