The habit of negative self-talk, where you constantly criticise and doubt yourself, plays really bad for your self-esteem. This does not just cause stress, but also anxiety, inferiority complex and in turn, bad mental health. This way of demeaning yourself can really influence your behaviour towards you and when these attributes start to shape you, it also puts a bad impression on others. To prevent this from happening, it is important to challenge negative thoughts. Instead of criticising yourself and dwelling about what you did wrong all your life, think about how far ahead you have come from the point you started. If you could not clear a certain examination, don’t give yourself a hard time. Instead, think about how much you have learnt while preparing and how it all shaped you.
