how does one get better without feedback? i do not know....constructive critisism is good!....sorry its so short

my lack of words is what pushes me to get better/
and i watch as my vocab grows letter by letter/
a lyrical sweater made of flows that just continue to grow/
like a garden of words, that i continue to sew/
what do you know? i might have found my niche/
found a place to come back to when lifes a bitch/
my hands start to twitch when i have lines to spit/
but all i can do is hope that they hit/
lines that fit, seem to be so rare to me/
but as i get better i find that i can see/
what ill be if i stick to this game/
even if right now i sound pretty lame/
