Is it especially self-congratulatory?

> I've loved, laughed and cried

> I had my fill, my share of losing

> And now, as the tears subside

> I find that it's all so amusing

...

> That record shows I took all the blows

> And did it my way

It's someone looking back at his life, who was sad about the failures, but is now at the end of his life and is proud that he made his own choices, took his own path, and endured the blows that life deals you.

He did life his own way, was unique in certain ways in an uncaring world. An existentialist anthem. A bit sad. A bit happy. A song about life.
