Small and medium-sized businesses are facing so many challenges in today’s competitive business environment.

Sometimes difficult situations, such as arguments or miscommunications, can cause people to become angry and instead of reacting the way that they should, they overreact. Of course, it is important to react to situations and feel emotions when we should, but there is a difference between reacting and overreacting. Overreacting to a situation can be off-putting and it can cause rifts between friendships. Learning how to regulate yourself and your behavior when you are angry can help keep your relationships healthier.
