laziness is a symptom IMO, often a self-protection mechanism out of fear.
I've met many people that decided they'll rather not do the thing than see themselves fail and prove whomever triggered that fear right.

Also IMO, when wired differently, some tasks are easier and some tasks take more work, but if we let ourselves (and others) judge us for how easy or hard a task is for us, we condition ourselves to avoid the latter.

Then again, I know people that had the right support behind them, and even though they initially sucked donkey balls at the thing, they powered through it and became mediocre, but very happy.

I want to be mediocre and happy. :)

Note: There's no judge harsher than ourselves.
