Great use of “lean in.” You should decide if you want to talk in the third person (“the company”) or the second person (“we”). Right now, it’s a little confusing…I’m not sure if you consider yourself part of the company or not. You can say: “If we want to grow our market share next year, we need to lean into our strengths like advertising and our YouTube channel.” Or, “If the company wants to grow its market share in the next year, it needs to lean into its strengths like advertising and its YouTube channel.” See how those are different?

Fantastic example of “lean in.” We don’t typically use the word “take” with “training.” It would be more common to say, “He took a long and detailed technical course for that position.” Also, “position” is like a job with a specific company. I assume the course or training has general skills, so it might be better to say, “…training for that career.”

This is a good time to use a gerund, an -ing form that turns a verb into a noun. So you can say, “There is a big difference between having a dream and reaching it.” In the second sentence, you would not use “his” unless you’re already talking about a specific person. To keep it general, you can say, “Usually, it’s necessary to lean into a dream for a long time before achieving success.”

Perfect!
