Sometimes, I claim that, although I'm 'trying', some aspect of the programme is 'difficult'. It rarely is, in the sense that assembling flat-pack furniture, replacing the wheels on a suitcase, or the use of modal verbs in Slovene is difficult. What I usually mean is this: I find it unpleasant, so I'm not doing it. It's unpleasant, not difficult, and the problem is not difficulty but unwillingness to feel the associated unpleasant feelings. It should be noted, also, that trying means not doing something. If I'm actually doing something, I never refer to it as trying. I'm eating my lunch means I'm eating my lunch. I'm trying to eat my lunch means I'm failing to eat my lunch because the process is being interfered with.
