Imperfectly practised

If no one is perfect.
Why is there a saying that goes 'practise make perfect'.

Its more that a headache I'm suffering.
Its MIGRAINE.
Weeks past, sharp pain on my right-side oh my head.
What if its worse than that.
Aunt(doctor) say it might due to high blood pressure.
Which is caused by STRESS.

Need to get well soon, time is ticking.
Project work has been stagnant.
