In most of the cases you will probably be bad at it when you begin, And that is completely fine - ESPECIALLY if you did not have experience with doing this before.

You will start by not knowing what you are doing and you will add/invite people who you think are good - AT THAT PARTICULAR MOMENT IN TIME.

If you are looking and interviewing, get in the habit of doing these 2 things:

1. Pipeline
2. Review your pipeline every month

You will be surprised to see how people you THOUGHT were good one month ago seem like a "warmup" compared to who you will be meeting later. It is a natural process. And if you see it and feel it you are on the right path.
