Question

Why consistency (repetition) and community is necessary to enhance our skills?

Answer 1

See

consistency is the only mechanism to make our base strong so that we can enhance our skill

Cause without a strong base one cannot go higher

Now the community plays a key role too as with it one can continuously judge their faults and their strong points so that they can enhance their skill

Answer 2

You can argue that consistency is a trait and not a skill, and there are some aspects of it that are. But if you view consistency as always getting your work done before the deadline

community--

Over time, as others at the firm realize how consistent and reliable you are, these activities get you noticed. Along the way, you may even find a more efficient process or new procedure for doing something that adds firm-wide value and is sure to get you noticed.
