A lot of people doing otherwise everything perfect get frustrated -- because they're doing too small of a volume of action.
If you're trying to build a new business, you might need to go talk to a lot of prospective new customers while you're getting your sales process down.
Yes, by all means, continue to refine and improve. But even if you're perfectly on the right track, doing not enough will make it seem like things aren't going well.
You can do that by working faster or by cutting unproductive activity and re-deploying that time into doing the right things.
But really, it's not a time issue. It's an expectations issue. Lots of things take a lot more work than seems like it should, especially early. But if you do it, you break through.
