I'm the exact opposite, I enjoyed 1-60 Fishing because I could sit in one spot and just relax. Had a macro that would /hook,. /wait, /mooch, /cast essentially making fishing a low attention activity for me while I did other things on a different monitor. At 63 you unlock spear fishing which makes fishing like mining/botany(node chasing) except you have to wait before you strike the node for a bubble burst indication on the node, otherwise you immediately miss/fish got away and waste durability on the node. For this reason I find that spear fishing requires the most amount of attention/brain power out of all the gathering jobs and it has slowed me down leveling. On the flip side, spear fishing yields fish that are required for some higher level recipes and on my server are still in demand so you can make a decent amount of gil just leveling.
