decide / conclude / come to the conclusion

Question

Here's the context.

The reason I quit my last job wasn't because it was bad or anything. In fact, what I do now is more or less the same. It's actually even harder(more difficult) in some ways and there are plenty of things that I miss about my old job. It's just that I had certain goals in mind and I decided that working there just wasn't in line with what I wanted to do going forward.

.

1. I decided that working there just wasn't in line with what I wanted to do going forward.

2. I concluded that working there just wasn't in line with what I wanted to do going forward.

3. I came to the conclusion that working there just wasn't in line with what I wanted to do going forward.

I feel they are different but I'm not sure what exactly the difference is.

Could you let me know the difference? Thanks in advance.

Answer 1

There is little difference.

"Conclude" means at the end. So it implies "At the end of a thinking or after a logic process". On the other hand you could "decide" quickly and based on your feelings or judgement. "Came to a conclusion" is mostly a long way of saying "concluded" but suggests an even longer process.

Three brothers each chose a sword. The first decided to choose the one that looked nicest. The second investigated the balance of each sword and concluded that a Japanese katana was best. The third discussed with his family and friends and came to the conclusion that fighting was wrong, so left to become a monk.

In the example you gave, you could use "decided" or "concluded" or even "cam to a conclusion"
