need some help about singing and help about instrument (and other things that might be off-topic)

[deft sandal]

ok so....i been quiet on this server and found out i could do this (which i shouldn't known better) but i need some help and got questions as well let start with my sing and instrument (note:i add my week practices for my singing and guitar which is 5 weeks)

now first off i got an electric guitar and to be honest i got this one possibly a few years ago (like xmas and stuff) not sure when i got that to be honest and more honest....i didn't play that guitar cause i was young and stupid and put that thing in the attic and found it in 2015 and then 4 years has pass at the guitat place i was at and yeah....didn't play it (i know i am an actual idiot i'm stupid) but i do know how to play it just a little and just need some practice and all that, and my question is how ling will it take to practice on the guitar? is there a fastest way to keep practicing?

now the second is my singing practice now how long is to keep singing practice? and when to tell if you already well ya know good at singing and such? like here's one of singing i practice on (sorry if the titles like that i don't know how to name it like that) and also i got a friend who tell me breathing would help (obviously i'm using one of those singing practice on youtube so yeah) she even tell me that drinking tea or warm water would help as well (honestly i don't drink tea so yeah) but is there a way i can do with my voice?

now third the off topics (it's between my drawings and my age i'm little worried about)

drawings
now before i ask/talk about this my drawings is more like manga (japanese drawings of course) now i'm trying hard and practice drawing (and the difficult/challenging part is that i'm dealing with hands and i promise to you guys but hands are difficult and tricky) and mt question for that is how long is for manga practice? and is there a fastest way to become one as well?

last on and it's serious/worried
i'm 23 and worried i'll never complete any of this and and worse i got a friend who is 29

(continue from age) as i was asking i got a friend who is 29 and she be 30 later this year i mean should i be worried about aging while my friend is gonna be 30? and i'll never achieve any of my dreams to become one? and what's worse that i didn't gone to college

(it's a long story for that)

@deft sandal vocally and guitar wise you could take as long as you want to learn

The earlier the better but if you have proper technique you could sing for a few decades

23 is still quite young in the music sphere (You aren't that much older than I am I'm 19 going to be 20 in july)

Stuff like tea coffee and hot showers and the like are a way to help open up your throat alongside warmups

Resonance is an important ascpet of singing and I don't hear much of it in your voice

I'm down to talk guitar and vocals with you

(Vocals are more my strongsuit though so keep that one in mind)

oh man i thought no one was gonna respond but yeah we can talk about guitar and vocal as you you know how to help and all and what about drawings?

also 23 is still young cause i got a friend who's gonna turn 30 later this year

honestly i get worried and sad about aging and such

Drawing isn't my expertise but I know people who can help with that
