Life includes sadness. Sometimes it comes to us despite our lack of desire because the world depends on others as well as on ourselves to provide for our needs. Allow melancholy to run its course, though, if or when it does. Let your tears out if they are there. It demonstrates that your human emotion is still present. Let the tears run their course as well because they provide relief over time and ideally a brighter vision. Then, recover and reroute your course in the direction of your objective.
