In this particular post, here are some typos:

“You fail that test, you get a detention.” is a comma splice. Two independent clauses should be joined by a conjunction and a comma or a semicolon.

“As we grow up this idea is lost.”

There should be a comma after “up.” When an independent clause precedes a dependent clause, it should be followed by a comma.

“I think the power of failing to succeed is described by Robert T. Kiyosaki wonderfully. ‘Most people never win because they’re more afraid of losing.’”

The period after “wonderfully” should be a comma or colon.

“Successful people did not just succeed on their first go.”

“Did” should be “do,” or the sentence should be changed to reference a past event.

“They tried and failed and tried and failed harder and then tried even harder.”

I’d probably make this “They tried and failed, tried and failed harder, and then tried even harder.”

In general, maybe you should download grammarly. A lot of writers swear by it. Also, the two things I recommend to writers are to: (1) be authentic, and (2) spend a lot of time reading masterpieces.

Hope this helps!
