Knowledge is a process of piling up facts; wisdom lies in their simplification.
Simplifying things garners clarity and guarantees success.
If I were to attribute ‘Stress’ to a single word, that that word would be ‘Control’.

We could all, consciously or unconsciously, be control freaks, however we must be on the right side of the control continuum.
Perfectly okay to control your thoughts, responses, emotions and actions however NOT perfectly okay to control other people, their behavours, their opinions about you, their feelings. NOT perfectly okay to peg your joy and peace on specific outcomes.
You have maximum influence of your energy and spirit at this moment. perform at your peak, execute relentlessly, engage actively right NOW. Nevertheless, you must relinquish your need for control and you will relieve yourself instantly from stress. It would feel like a huge burden getting off your shoulders (back or chest), leaving your light and energised. Want evidence? Experiment with it today, over the next few interactions, open ourself to acceptance, let go of the illusion of control and experience the magic it carries.
Deeply contemplate on these words – Lord, grant me the serenity to accept the things I cannot change, courage to change the things I can and wisdom to know the difference.
