I'm just a beginner myself, started 5 weeks ago, but agree it might help to concentrate on the the non-measurable side of things - the beauty of the land arouond you, how much stronger you feel, how much less of a struggle a s#certain distancwe/time is, how much better you look, how much brighter you feel etc - rather than getting hung up on numbers.
I know you are used to comparing yourself against a number, and it is reassuring, but being capable and healthy is not a measure, and isn't guaranteed if you reach a certain number type goal.
Have you spoken to your counsellor about this sort of thing? it may help . . . . .
PS I'm not considering a 10K for quite some time - and I am very very happy with my progress - everything is a battle against myself, and the worth is in what I think - not from comparing myself to others or preset numbers.
