A life without purpose or meaning probably results in a low level of motivation to act.  When there is no reason to do anything (purpose or meaning) so one does nothing.

The exception to this is when doing nothing is your goal, i.e., it is what motivates you and so your behavior is geared to enabling you to do nothing.  If this meets your purpose, it is perfectly fine.

Your goal is yours to select, however, there is a primal driver that overrides your choice of purpose, meaning or lack thereof.  “Pleasure”.

Seeking Pleasure

Pleasure is simply a term to describe a state in which you have a feeling of happy satisfaction and enjoyment.  That is, pleasure feels good.

I theorize that pleasure is the primal driver forming the underpinning of my own personal motivation (and probably that of most people).  Simplistically, seeking maximum pleasure is a component of everything we do (i.e., feeling good).

It’s all about me

Pleasure seeking does come with some constraints.  If someone else is suffering at my expense I do not feel pleasure.  Fortunately, this is true for most of us.

Those who derive pleasure without regard to context are usually labeled as deviant even criminal in their nature.   Intrinsic to the human condition is a level of empathy.

Some are more empathetic to the plight of others, possibly influenced more by nature over nurture.   Generally though (excepting the aforementioned deviants and criminals) everyone exhibits some level of empathy toward others.

Embrace your inner desire to seek pleasure

For me, seeking maximum pleasure (as long as it’s not at the expense of others) is natural behavior and there is no reason not to both recognize but also embrace it.
