“Making Allowances”
It all depends upon what you mean by ‘allowances’

We start at our ‘Square 0
{or ‘Square –n}

Get all of the [your] facts-on-the-ground
and then your needs-&-hows,
rightly matched
by the words in your mind, written-constitution, and action-plan.

Only then can you have any expectation,
or even slightest-hope,
of even ‘as-is’ succeeding –
let alone ‘sustainworthyingly’
