I actually find the gathering classes (all three of them, though fishing seems more fun) relaxing. And that is from 2.0 to now worth of gathering/leveling those.
But yes, the best way to level them faster, the Grand Company Provision system is the thing you want.
Crafting is much more stressful to me. Especially with that harsh increase between 2.0 1 Stars and 3.0 no stars which are likely 4 stars. Still it is a tad more fun as I have learned a few tricks to do what I need to. I finally got a crafting class to 54. Oo It is sad that it takes hours for my Gathering Phase and only less than an hour for my crafting phase. (I mainly only have been doing the supply and provision thing. >< While my gathering has been fueling my gil needs)
