This is all due to lack of confidence. When you fear something or for that matter you are angry or excited over something, stop thinking about it. Feel the knot in your stomach or the lump in your throat. Take a deep breath.
Instead of getting worried about efficiency, try to pinpoint the reasons for not being efficient. You must know that your energy, passion and enthusiasm fuel efficiency. The best thing is to do something exciting like planning your next holiday or just sit in your garden and enjoy the greenery and floors. Let the stress get out of your system. Thus you can find new ways to make happiness and enthusiasm your normal living.
Better know that your brain feeds you what you want. If you think that your life is a struggle and you will not get what you want, you are always at the end of the queue. If you think the other way round that you are fortunate and life does treat you well, you will feel so. If you want to change your life, be positive and paint a happy picture of your life. So every day make a summary of what you want and write it down. Think about it for at least 15 or 20 minutes. You do this exercise every day and your brain starts working the way you want. In no time your brain makes new connections that search for new ways to achieve your ideal life.
We are conditioned to think that life is a struggle and only the weak seek help from others. This attitude kills your enthusiasm. Get rid of this picture of life, go out and seek help. You get positive response as everybody feels that he is valued and his opinion and experience count. But take what others offer you with a pinch of salt as they give the picture they are conditioned to see by virtue of their wants, aspirations, likes and dislikes, hopes and disappointments. All this may not be valid for you. So always ask people what you want to emulate. Avoid naysayers. Find only the right person.
You have to be open and speak up so that people can know what you are and what you want. If this is clear, you will get sane advice which you are in search of, perhaps leading you to your cherished goal.
Sometimes you dismiss an idea or thought as silly when you think it is abnormal. Get away from this habit since such ideas and thoughts come as flashes from our subconscious that always sees the bigger picture of what we desire. Your logical mind is less capable than what you think. So follow these flashes and test them bit by bit.
What all has been suggested so far should be practiced regularly on a daily basis. Give all these tips some time to give you results. Don't worry about them all the time.
