purseverance

Refers to an unwillingness to give up on your efforts to mooch off of someone (in other words, to get him to "open his purse" for you).

Sometimes the term "purseverance" can have a somewhat opposite meaning, as well --- it can also refer to the ongoing efforts that an overly-trusting person who actually HAS "opened his purse" to a neighborhood moocher feels compelled to maintain in an attempt to get said deadbeat to pay him back as he'd promised he would.

perseverance 

to finish what you started regardless of the obstacles that stand in the way.

I will choose to live my life with perseverance when it gets hard and uncomfortable so that i can achieve the goal that is in site.

Pereverance

A means of being in an infinite state of awesomeness.

The friends of the bride and groom partied like their pereverance was only getting better.

Pussyverance 

The act of continuing to pleasure a woman even when orgasm seems not to be happening. Keep going, never stop until she climaxes.

Her: Babe, I just can't cum.
Me: No, I got this.
Her: I'm trying, it's not working.

8 minutes later... Orgasm success!

Me: See babe, my pussyverance paid off.

Perseverance Rover

The NASA perserverance rover is a rover that used MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment) to generate a lot of oxygen (122g) from carbon dioxide by splitting it with a catalyst insulated by aerogel.

During the process of separating the oxygen atom, the temperature rises to 798° C. In this regard, MOXIE has received a gold coating and an aerogel. The presence of heat resistant materials ensures that heat is retained inside the tool. The Perseverance rover extracted oxygen from carbon dioxide 16 times, leaving carbon monoxide as a byproduct. Oxygen is good not just for future astronauts to breathe, but also to fuel rockets.

NASA: We synthesized oxygen from carbon dioxide in Mars using the Perseverance rover and an insulated catalyst.

Belief Perseverance 

A cognitive bias. It's fairly similar to confirmation bias except an individual actually receives information that discredits or contradicts their beliefs but continues to cling on to their views out of stubbornness.

Elmer doesn't think Donald Trump is divisive even though I showed him a video proving otherwise? Man, he has belief perseverance issues.
