I ran intocame across the word "rashly" when I was reading an article.

"ran into" = when you meet someone unexpectedly that you know (e.g., I ran into my friend at the grocery store); you cannot run into a word

I added it to my flashcards and wrote down a sentence which consist ofthat included it in order to understand this word more deeply.

Here's the result: ¶

I added it to my flashcards and wrote down a sentence which consist ofincludes it in order to understand this word more deeply.

We use "consist" when we describe the building blocks of some larger thing as a whole, rather than focusing on a single component. For example: "A sentence consists of words." "Human body consists of millions of individual cells working together." "My daily routine consists mostly of watching old movies and playing with my dog."

"If you want to be successful in the long term, try not to make big mistakes rashly rather than try to do everything right.to do everything right rather than making big decisions rashly."

"Here's the result" is not wrong, but it is a bit vague (the result of what?). I think the suggested way better connects to the previous sentence.

"X rather than Y" in other words means "do X, not Y". "Not X rather than Y" doesn't feel quite right ("do not X, not (not?) Y?"), so I would recommend to keep the positive part in front.

Also note the clause grouping: it's "try to (X rather than Y)", not "(try to X) rather than (trying to Y)". You can use the second form in some situations, but here it is redundant.

Finally, "rashly" is typically used to describe actions rather than outcomes. People rarely set out to intentionally make mistakes, but they are an outcome of acting rashly.
