Leaky

The leaky wooden bucket has given up on itself just because it can't perform like it used to, especially when compared. The bucket, however is unkind to judge itself so harshly. The leak watered and grew beautiful flowers along it's path, and in the end still held enough water to help fill the pot.

Oh, that was what the last panel was about.
Don’t forget that it also helps to keep it balanced with the other bucket.
- Very true

There’s clearly something I’m missing. I don’t get it at all.

Leaky bucket watered flowers along the path!
- Thank you! I was slightly confused as well.
My interpretation, the leaky bucket is watering the side of the path, why you see all the blooming flowers in the final panel. While the bucket is feeling like it's worthless and not as good at the task of hauling water, it has an positive impact on things around it's world.
The incompetence of the bucket allowed flowers to thrive, leading them to eventually achieve sapience and overthrow the farmer. It was during the renaissance after the post industrial age of flower society that a new peaceful era dedicated to the worship of the wooden bucket began.
- Incompetence?
  
  Maybe old age. Or lack of self worth. Or grief. Or inexperience. Or... are we still taking about a bucket?
- All hail The Wooden One!
- Until the farmer sends his tank... umm... his plow.
It’s a funny comic because buckets can’t talk

When these people are fired for "not doing anything important", everyone else's work suffers.

What... Does pro level: expert mean?
- Pro is short for professional
I gotta teach my wife this word.

… there’s a hole in the bucket, Dear Liza dear Liza

Then fix it, dear Henry, dear Henry, dear Henry.
- With what shall I fix it, dear Liza, dear Liza?

Cute but what's the takeaway here? Your shortcomings help others?

If you're not good at the thing others expect you to do, you may be good at something else.
- But you might still get fired for being a leaky bucket? Thus not getting the chance to water the path anymore?
Work harder for the bilionaires to enjoy flowers
Inefficiency may have positive side effects to the point of being not inefficient at all, but different
Retirement is bad! You should keep working even if you're worn out and not fit for purpose! Keep laboring!
Don't throw away the bucket, think how a little flaw may be beautiful and even useful.
I don’t get it either, does the water holder want to water the flowers? Cause otherwise it’s still a bad bucket

The water source is higher ground than the house... Dude should just build a small trench for the water to flow down to his house

At first I thought the flowers were fallen apples and I thought it was about finding a new use. Either way, it's a positive sentiment.

Shouldn't the flowers be on the other side of the path?

Water drips on the way from the lake, not towards the lake.
- Yup! You’re absolutely right. 🤦‍♂️
