Procrastination describes that speaking or doing things is not simple and agile, indecisive, decisive and resolute, and greasy means nagging and complicating simple things.
If you want to change this state, you need to build up confidence, study more, think more, face it bravely, learn to ask or learn from others, pay more attention to details, affirm your own ideas, keep your enthusiasm and keep your personality. This will change the indecisive character.
