As someone who's come from an upper middle class family, got rich in early 30's, lost all money over women and got poor in mid 30's, got rich again briefly afterwards, got very poor again afterwards living in a shelter, and then finally got rich yet again... I can attest that every time I got back up, I pulled myself up by my bootstraps. It was a very effective technique. I recommend it!
Joe: Mom, they fired me from the job! Said I can't code for shit!
Mom: Just pull yourself up by your bootstraps son! Life is tough, but you gotta be tougher and beat it!
The Bootstrap Paradox is a theoretical paradox of time travel that occurs when an object or piece of information sent back in time becomes trapped within an infinite cause-effect loop in which the item no longer has a discernible point of origin, and is said to be “uncaused” or “self-created”.
A time traveller who was a big fan of Beethoven goes back in time to 18th century Germany to search for Beethoven for an autograph. Upon reaching the destination, the time traveller cannot find Beethoven anywhere, not even Beethoven's family have heard of him. Not being able to bear the thought of a world without Beethoven's music, the time traveller coincidently has all of Beethoven's sheet music, he copies it up and publishes it. The time traveller has become Beethoven and the timeline resumes as usual, this is what we call a Bootstrap Paradox.
