It makes you wonder.
Walk into any library, book store, second hand shop or wherever they sell media. Look at the hundreds of thousands of book, albums, DVD and I wonder how many of those folks were doing it trying to make it big, grab attention or turn it into a career?
And that is a very VERY tiny slice of the entire pie. For everyone successful artist you find, there are hundreds or thousands that never got lucky or had the skills to make it. I put luck first deliberately.
A good example, based on the IBSN listings there are currently 158 million unique books. That is one unique book for every 53 people on the world, how many can you think of?
I love going to old book stores and pulling out something random, usually some paper back from the mid 60's/70's on a topic you probably never even thought of. How much time and effort went into writing that, editing, producing, marketing it? I look up the authors to if they ever made much of it all, about 99% of the time, their name doesn't turn anything up. Despite their published works, they could still be alive, they are already forgotten under the sheer volume of works out there.
There are TV shows I remember, they had whole crews working on it, actors, writers and producers. The only proof they exist online is about a paragraph or two, didn't even get a wiki page. To be appreciated by those close to you, that should be more than enough, but for some it has to be broader, I do not know why.
I think a part of it is that many people come into this world thinking it is a race. I say, IF and that is a very big if; if life is a race, it is a 100meter race and it doesn't matter what position you come in. Saunter your way, take the long way. And yet when you get to the finish line there are loads of people racing past mocking you and desperately trying to convince that "You think that is the finish line? Nah, this is marathon and the real goodies are there!". And so they keep running as fast as possible, wearing themselves out and getting exhausted to no end. The joke being that there is no other finish line.
You can be content in you, content in now. Just be chill... damn it!
