Is there really a such thing as “second chance” in Life?

In previous topic before this, I’ve talked & admitted about how I’m still jobless now,.and still living with my parents. I feel so ashamed, and especially for my parents, who are admittedly much more ‘practical’ than me & my ‘head-in-the-clouds’ imaginative personality,..which can act like a damn “curse” quite often. and all the ADHD, bipolar, easily bored/depressed/lose focus,..stuff like that!

So now, here I am,..almost 29 yrs old,..and still a fucking ‘loser’ as far as I can see..
and although as much as I often said that I don’t CARE about what society (even my family & parents & relatives!) keep saying, bombarding, pressuring, and scorning me about my damn ‘jobless’ dire situation (plus still apparently my huge, deep interest in being a Musician/Composer/Songwriter,..and an authentic/idealistic/visionary one at that..apparently this even drives my parents & some relatives/friends even more crazy!),..
yet, I still can’t lie that the forces of Reality is really a damn STRONG one,
and really,..I’ve found,..that in recent months (even in recent almost 2-years!),..all the ‘escaping/escapism‘ really do is just to further make my situation even more WORSE,..at the long-run!

So now,….I often really feel like so scared,..if whether my “Time” has already passed!
that everything is already too DAMN LATE!..and I WON’T be able to return back time, and chances to amend again!..
and even just thinking about all of these, can really make me teary-eyed and moan in anguish, during my lonely time..

But what I want to ask is this: is there really such a thing as “second chance” in Life?
Eg: since the “first half” of my life was messed-up,..I’m hoping for the “second half” of my life to have that ‘second chance’…
You know,..sometimes I do read encouraging, motivating articles like for example this one about “Late Bloomers” from wikipedia, and the examples there sometimes can really encourage me that it’s still NOT too late to fix all the ‘broken’ things in our life, and obviously, to succeed in one.

But to be utmost fair, I’ve also heard the common-phrase that “for every ONE person succeeding, there are probably HUNDREDS persons failing!”
meaning that in REALITY (this so-called damn “Real world”), the chances of even ‘succeeding’ in life (let alone becoming ‘famous’!) is just soooo miniscully thin!
So, for many of us,..does Life really include only failing & being miserable & in difficulties, pains, and sufferings??…then why should I keep living then???

What do you all think?
And can any of you here relate with my life experience?
