The willingness to take a risk does occasionally arise, and when it does, there's a chance the risk will be successful. I don't hesitate to take a risk and try something new or different, even if I don't succeed. I'll be glad that I took a risk.
In life, taking a risk on something is preferable to not taking any risks at all. No matter how many times you fail, taking calculated risks is the foundation of success in the world we live in.
