Hmm

You'll see plenty of examples around you – alcoholics, drug addicts, homeless people; these are all people who have fallen and lead a terrible and miserable existence, which can only be conditionally called "life." Do you really think they don't commit suicide because they have a strong character?

I think they don't commit suicide because they lack such thoughts.)
There's clothing from someone else's shoulder, year-round potatoes (or whatever is now common among those leading a miserable existence; Lock writes that it's worms, so let's say it's worms), and entertainment in the form of booze and a similarly unfortunate member of the opposite sex nearby.
What else is needed? What's the reason to make a tragedy?
Again, this is the limit of possibilities. "You can't jump higher than your head." Of course, you can complain that the booze is expensive and the partner is cross-eyed, but would you kill yourself because of that? You're kidding, right?

In general, IMHO, it's not enjoyable for everyone to break through their own ceiling; many are already doing well. And many don't even think about the possibility of moving to a new level. So, the example with the homeless isn't very good.

Here's another example.
A young scientist, who showed great promise in school and, of course, in university, decided to commit suicide at the age of 27 because by that age he had still not made any groundbreaking discoveries and wasn't even on the path to making them. "Since there are no discoveries, it means that the hopes placed in me were false; I am worthless, and my life is meaningless."
At the same time, he already had several students (also promising young scientists) and quite good educational activities, which had earned him fame and admirers in narrow circles.

What do you say about this? Strength or weakness?
