Perfectionism can take place at the cost of getting things done. It can leave us starting projects we never finish, or never even start due to the fear of failure, or not being "good enough". Jesus talked about it in Matthew 25, and stresses that we cannot allow fear to rule us to the point of where we "bury our talents in the ground." Don't be ruled by perfectionism, don't be afraid of making mistakes. God doesn't expect perfection in our works, but rather simply our best try. And when we give God that, He has a promise in store: More talents!
