This is assuming:
1) that you know yourself better than anyone else knows you
and
b) no two people know opposite things about you (ie: one person thinks
you're too cheap, another that you're too extravagant.) And don't give me
that "reality vs. opinion" schtick, because they are one in the same.
And i won't even touch the subject of how we lie to ourselves about our own
nature.
In other words, you can't accurately plan for information without taking
into account disinformation -- that given to you by others, that you give
others, and that you give yourself.

he proceeded in fits and starts, backed up, edged forward, backed up, while
other ideas zoomed past close at hand."
