If someone across the world can work 8 hours a day manufacturing dildos in a factory then why should I not be able to do the same with music regardless of whether I feel happy or not?
There's no demand for your music.
That's the answer to that.
The mindset isn't about where you're getting paid to do something, it's the motivation to DO that something. You think that dildo maker was growing up and saying "one day i wanna make dildos until i die"?
Problem, is that the emotional state when doing things make it all the more difficult to actually do the things. The part that makes us human, is also the part that pretty much dictates our choices. We have words like obligation to describe that state.
So, once again, this is purely getting up and getting to work. What makes you actually get the fuck out of bed in the morning?
It's not a shared mindset, it's THEIR mindset because IT WORKS FOR THEM (caps for emphasis), they don't know you, they don't know what you do, they don't know how you really are.
Do you even know who/what you really are?
and then, because of your persistence, always goes back to a deeper state of understanding the self before you can really become accomplished in life.
or at least understanding it enough for you to learn to grow.
Attitude makes you get up from falling down, and make it up the hill. You can still crawl if you're not dead. You only stop when you're dead, and completely done. Other wise, you move as far as you can until you get to your goal. (just don't be a dick, because people will help you).
And if you're not doing that, then you're in the way or something is in the way. But you can still always crawl.
