There is a pre-ordination about purpose that supersedes time, merit and ability. Because it is not our own, and was allocated in its full measure, prior to our understanding, its ability to be fully actualised is only dependent on our ability to 'search it out'.
In the same vein, the instant a foetus is formed, it possesses (within itself) everything required for it to mature into an adult. Initially, the foetus is not aware of itself, didn't particularly deserve, or, utilise any special skills to attain its DNA. It was given by its parents!
The onus then lies with me, the onus lies with you, to search and discover what was given to us. Be confident in the truth that, you are enough. As you go through the day, ask yourself, "What is my purpose DNA?".
