‘when my posture weren't so steady’ - I really like the use of ‘weren’t’ here

I chose a "gate" comfortable for me – for rhythm’s sake – ‘comfortable’ is a little long to my ear – would ‘suitable’ be suitable? or ‘agreeable’ even?

also here as well as in
‘Changing "terrains", and tilting "grades"
gave my "giddy up" it's signature’
and
inexplicably seem to "fade"
and
‘underneath great listener, "Gnome".
– I’d remove the quotation marks – I really don’t think they are needed and imho actually detract from the write

‘No hidden agendas in my hand’
- somehow I keep coming back to the ‘s’ – I think agenda sounds better singular

‘while bright, perpetuating colors’ – ‘perpetuating’ a little long – maybe ‘perpetual’ ?
‘cause sweet, blindness in my eyes’ – I’d lose the comma

‘I've found a monkey in my pocket
with my keys outside my home’ - love these lines

as well as
‘be careful when crossing any street,
and have, (in case), clean underwear’
I love this – we can all relate to these pearls of wisdom all parents share
-one thing
-‘have’ seems to denote to carry
-perhaps wear’ ?
‘and wear (in case) clean underwear’

some punctuation problems with the write
for example, the line just used – commas are not used before and after brackets. and I think you have overused the semi-colon… and put a couple of other commas where they don’t need to be
ie
'heal, and conserve'
'Changing terrains, and tilting grades'
'boundaries, made'
'weeds, and roses'
'done, and said'

but I so enjoyed this read
