Supposing about it over and over again
In the beginning, this might be like a softening exercise. But, the idea is to make you resistant to situations inspiring perturbation in you. Supposing about a frightful situation over and over again would piecemeal make you lose the fear of it. You would run like used to the script in your head. This exercise is synonymous to the representative of repeating the same word for a while till you lose the understanding of what it actually meant. This process is named semantic inappetence.
Act upon it
Once you’re done with the intellectual practicing, go ahead and put yourself in a real situation. Take a step forward and strike a converse with that person whom you had been wanting to talk to for since long. Come in the catbird seat and give the speech. It’s the negative feeling and fear that had been holding you back. But, remember you have done your share of lectures and it’s time to test yourself. Try not to be too critical and harsh upon your performance as it’s your first factual step. The fact that you confessed your issues and took the track to clean it, counts.
Accept review favorably
Your leader or your preceptor might be dispraising you at the moment only because they find the amazing rate in you and want you to strive for excellence. While on the skin it might come across as harsh to you, but realize that they’re trying to dig you out from your comfort zone. Yea if not appreciated in a healthy light, don’t go back to being a nervous wreck. Mind to those feedbacks and act upon them effectively. There’s nothing to lose presently but only achieve.
