I would willfully like to draw attention towards understanding distinction between Manage and Control. The above mentioned content in this text will provide enough insight into understanding Emotions and their origin, but as we know knowledge is double edged sword, it is important to use it well.
Let us understand simple distinction between Manage and Control
While we experience negative Emotions, of course they are undesired (because they are experienced when you have not achieved what was Desired), how we focus on desired positive Emotions is an art that one masters only over a period of time. Negative Emotions have been there and will always exist. Their presence is indication of an opportunity to focus on improving our Know-How, learning how things actually work and be more practical in our approach (be pragmatic). While we Manage Emotions, presence of negative Emotions is not be ignored or suppressed, rather they are to be accepted as a part of life and embraced. Give them the space and attention they demand. Give them the time they need to settle and the time they demand to analyse what went wrong, what could’ve been done better, what is realistic and what to expect in future. Think of that time when you were really Sad, you did not have what you really wanted. You wanted to spend a lot of time alone trying to think about what went wrong and how you lost it. You wanted to cry or felt angry as something/someone took that away from you. In that moment, did you suppress, ignore or avoid your Emotions or did you embrace them and gave them the time, energy and space of mind they demanded? Ofcourse you need to move on to positivity in life, but as much important it is to manage your positive Emotions, it is in fact more important to manage your negative Emotions (as they are undesired).
