Since that is your title, it should follow the capitalization rules.

The article "a" is unnecessary before "my education." "My education" is a noun phrase that doesn’t need an article

All of those are great, but my education lasts a lifetime.

"I've received a lot of good gifts" is more naturally written.
I added em dashes (—) to set off the list of items, which makes the sentence flow better and feel less choppy.
