When we speak any language other than the mother language, we in fact use a filter inside our mind. The filter bars the words of mother language, translate them into foreign language and then pass on. This filtration process on one side, decreases the ability to express and on the other side it slows the creative process as the a part of brain is constantly engaged in translation. The thought always erupts in mother language. if we process the thought in mother language and then express in mother language, we can be more creative and more expressive.
