Jellyfish are built for drift, they move with the currents and the tides in beautiful clusters of life constantly in gentle motion.
Drifting is great for Jellyfish, but what about people?
Is there anything really wrong with 'going with the flow', or seeing where life takes you?
If drifting for you means remaining open to opportunity, not creating attachments to soul sapping endeavours and allowing exploration to the edges of your journey, then drift.
If your drifting is aimless however, the anxious and unsatisfied squirming in your gut should be answer enough.
