I just bathed in the glory that is the So White bath ballistic from Lush. I smell like the lord himself kissed me after eating a crisp green apple. This is a simple lesson, but it's one I feel you should fairly easily apply to everyday life: Smell good.
All it takes is a teeny weeny bit of effort to eliminate your natural stench and adopt a slightly sweeter one. I assure you it will make life that little bit better. It will not only bring confidence but will remind you that even if everything falls to pieces, at least you smell good and have that under your control.
Simple, smell good.
