Is this sentence grammatically correct? (I need it for a personal essay.)

As I look back on my life, I realize I have completed many accomplishments, cultivated beautiful personal relationships, and created a strong legacy to be left behind.

It makes sense but is rather long it would look better if you broke it down into two or three sentences.

As I look back on my life, I realize I have completed many accomplishments. I feel I have cultivated beautiful personal relationships, and created a strong legacy to be left behind.

I think it is redundant in two places. Completed accomplishments? Accomplish is defined as completing. How about "achieved many goals".
A legacy can't be left anywhere except behind.
I would suggest "and created a positive and inspiring legacy"
I am just trying to get rid of the redundancy and this is just my opinion.
