Most games are easy to learn and hard to master.
FM is hard to learn and easy to master.
It is a brutal learning curve for newbies - hugely complex, fiddly, unintutive, poorly explained, easy to miss things, easy to misunderstand things, easy to get into a downward spiral where nothing works.
Once you have figured out the various systems, mastered the UI, learned what matters and what doesn't, watched a few tutorials and scanned some threads here, it becomes pretty simple to over-achieve vs your club's real life position.
The irony is that having climbed the vertical learning wall, you need to make it challenging for yourself again by limiting yourself or creating challenges. I actually enjoy that element because I play to create (or recreate) scenarios rather than beat the game, but one guaranteed way to get a rise out of some posters here is to suggest making it hard for yourself by not doing the things that make it easy .
