Balancing your emotions and reasoning (logic) are like two sides of the same coin. Emotions whether positive (happiness, relaxed) or negative (anger, redness, fear, tension) makes one stirred up or shakes one’s whole being till you express them in some form. Similarly, logic, reasoning or practical problem solving is equally important to handle daily short term & also future long term problems. Both emotions and reasoning have to be balanced.
If one is too emotional, then one might not be rational and vice versa. It is always better to be practical but one should also be able to connect emotionally. The so called emotionally balanced person can live life to the fullest than the extremes of too emotional or too rational or logical people. Too emotional or too logical may disturb one’s smooth sailing.
