Let's not forget in a hurry how destiny works. Destiny works according to God's divine plan for one's life, when the person has taken out time to discover what's he/she destiny is. There is this responsibilty of embarking on self discovery for destiny to take its root in that person's life. You can just sit down lazily folding your arms doing nothing and expecting destiny to work out miracle for you by making you to become what didn't prepare for.
Agreeably, I know sometimes, destiny works mysteriousy. In the sense that there are things we didn't expect but yet happen to us. Let's say for example, you've been trying out so many things you are good at, and the while nothing tangible was forth coming, but suddenly, the one you didn't expect materialize according to your destiny. It's would be appropriate for you to say that 'what would be would be' according to the popular say for destiny.
