Good work, Mohammed. I like your use of questions, and the way you describe how you totally goofed up.
A few minor suggestions:
Now you know problems are part of life. They’re here to stay.
=> This is an example of a obvious statement that you may want to turn into a question:
You know problems are part of life, don’t you? They won’t go away.
So I’m not going to promise you a life without problems. But what I’m going to share …
=> This can be shortened: I can’t promise you a life without problems. But I can share … etc
So knowing how to deal with problems is literally a matter of life & death
=> The word “literally” can almost always be deleted without changing the meaning of the sentence.
And it’ll be replaced with a feeling of gratitude.
=> this is a passive sentence you may want to change, e.g.: Instead you feel gratitude.
The next time you face a problem, instead of complaining in your head talk back to it
=> This is a slightly tricky sentence to comprehend quickly. You may want to cut it in two, e.g. The next time you face a problem, don’t complain. Instead, talk back.
