That feeling that you have not achieved much.

This can be a pernicious feeling that inveigles or worms
its way into our daily thinking processes.
I have been immobilised by it at times especially
when I view the success of contemporaries and
and start making (odious) comparisons.

What to do? One course is to come to terms
with 'success' 'achievement' as having been laid down
and reinforced as scent trails, by media, discourses,
experts, culture and the like.
Still, like barnacles on one's mind - difficult to prise off.
