Perfection comes when there is positivity in thoughts.

Projection

When we are faced with any weakness of ours, we usually think about
it so much that it is totally blown out of proportion and it seems
bigger than it actually is. This leads to negative thinking, which
in turn doesn't let us work on improving ourselves. We will then
just remain the way we are, not being able to bring about progress.

Solution

What we need to do in order to win over our weakness is to change
our focus. Instead of thinking about the weakness, we only need to
think, "I am not perfect yet, but I am working towards it and I am
slowly improving." With such positive thoughts, our negativity will
finish.
