Is it better to be a train that is fixed on tracks and knows it’s destination, or better to be a a plastic bag blowing where ever the wind

My late husband used to tell me I was a bag blowing in the wind, so I guess Ill choose that one. ;+

It depends upon the person.  Many need the security, stability, and surety the tracks provide.  Some of us cannot abide the rigidity, regulation, and regimentation of enforced conformity.  I would be among the latter.  :) 

(it's its destination)

i think its better to be human
