It's so tempting to rush through to the next step of the process before giving the current step time to set. The push is to keep moving forward with our momentum, even when the project just requires time to do nothing.
This phrase comes from the fun YouTube channel of Laura Kampf, who has a big block with the phrase on it. Viewers of the channel find the block simple yet profound.

Give yourself and your projects the space to set. Don't rush the outcome. Just because the glue isn't working yet, doesn't mean it won't work if you just give it time.
