What does this mean: 世の中は いっぱい いっぱい せいいっぱい 人生へこたれんなよ


This is from Midnight Diner and it doesn't seem to match the English subtitle
so was curious for a literal meaning and translation of this quote that I got
from Japanese subtitle:

> 世の中は いっぱい いっぱい せいいっぱい 人生へこたれんなよ  
>  Life is one hurdle after another. Don't lose heart.




> 世の中は **いっぱい いっぱい せいいっぱい**

seems to be trying to make a rhyme here. So, it may mean more of a figurative
manner and 'Life is one hurdle after another' sounds a good translation as an
aphorism in my first impression when you encounter a lot of difficulties with
a **full** energy.

  * いっぱい literally means 'full'.
  * いっぱいいっぱい is a set phrase and normally used to beyond one's control when one has too many things to deal with.
  * せいいっぱい literally means "Full energy".
  * へこたれる means gives up, so へこたれんなよ means "don't give up" or something like that.

There is a space in lyrics, so it does not explicitly say "いっぱいいっぱい” in a
complainant sense and it implies a flavor of the set phrase.

Therefore, it probably implies something like "there are so many things to
work on with your full energy to your limit" and "Never give up".
