The verb phrase “generations that will be born” (lines 3 and 4), would be incorrect if the verb “be” were omitted.

In lines 1 and 2, the words “weak” and “strong” could be correctly written in the plural form, as in “weaks” and “strongs”.

The verb phrase “What is worth it in life” (line 4) would remain correct if the pronoun “it” were omitted.

The phrase “in the end” (line 5) could be written as “at the end” without change in meaning.

The phrase “you will be able to reap what you sowed” (line 6) could be correctly shortened as “you will have what to reap”.
