My success has been something I've worked a long time at and it's been a gradual process. I compare it to the idea of someone losing a lot of weight over a period of a few years. You don't really notice the weight loss overall but if you compare photos from then and now there's a big difference.
A 'No' uttered from the deepest conviction is better than a 'Yes' merely uttered to please, or worse, to avoid trouble.
