Many can take excitement for nervousness, such that the flutter in their stomach brings them the opportunity of minor dread. Differentiation between the two comes simply from recognising if one is feeling fear toward the outcome/projected event. If so, then it may be a level of nervousness, otherwise it is excitement. Intriguing how the same physiological response from the body can form entirely different outputs from the consciousness. In the same way, one must be prepared to allow their feelings to exist with acknowledgement while holding the objective notion of their tilt. That even with excitement or nervousness, the outcome matters only to this specific thing, or that there is a backup plan. Where feelings can often provide the opportunity to spiral, it is to our duty to instil these objective blocks to ensure we stay experiencing just the one at that time.
