Bimbling

To amble without real aim, yet in a friendly and harmless manner.

It's not required to achieve anything whilst Bimbling, although it's aimlessness is a frequent side effect.

Bimbling can be made a little more business like with a slight hunch of the shoulders.

It is not essential that Bimbling should be a solo sport.

Blissfully bimbling through life without a care in the world.
