We communicate either through our presence or by expressing our feelings. Bring clarity in your communication and you’ll see people respond to you better, and more than often favourably.
You will get to know both, your strengths as well as your weaknesses so that you can work on them. You can take the advantage of your strengths when needed and can avoid the things you are weak at.
