Do I put a comma or semi colon?

For example, when looking at a subway map to plan a route or completing challenges from hack nights I attended weekly at Pace University I began to see patterns in everything I came across.

Also, what is the correct way to write the sentence below?

What we ourselves make of those vast opportunities helps shape and mold us into the persons we are to become.

Do I put a comma or semi colon? I'd break this up into two sentences. Neither a comma or a semicolon will help! I'm underlining your main clause -- everything else is extraneous or descriptive.

For example, when looking at a subway map to plan a route or completing challenges from hack nights I attended weekly at Pace University I began to see patterns in everything I came across.

So please turn all this into two sentences, and I'll check it for you.

I'd turn it all around. It's another sentence with too much that's front-loaded!

We are shaped and molded by the vast opportunities we are given.

For example, I began to see patterns in everything I came across, from looking at a subway map to plan a route to completing challenges from hack nights I attended weekly at Pace.

I am stuck. I need to mention that other stuff to be descriptive, but can't figure how to make it flow grammatically correct.

Also I'd like to keep the other sentence that way I just wanted to know if persons was correct or is it proper to change to people?

What we ourselves make of those vast opportunities helps shape and mold us into the persons we are to become.
or
What we ourselves make of those vast opportunities helps shape and mold us into the people we are to become.

Thanks so much

Both sentences are quite wordy. Read this and cut out all unnecessary, repetitive words:

Turn your first sentence into two sentences. Once you do that, I'll help you with punctuation, etc.

For example, I began to see patterns in everything I came across in my daily life. From looking at a subway map to plan a route to completing challenges from hack nights I attended weekly at Pace.

I am trying to be wordy and add details to an essay that wants description and details and must be 650 words.

Then keep your wordy sentences.

Put a comma after "University" in your very first version of sentence 1.

Keep your first version of sentence 2 unchanged.

So persons is OK instead of changing to people?
