Caring for the project you're working on

Sounds so simple, it's almost like a cliché. However, in the, rather interesting, words of a former teacher of mine "It's a cliché because it works".

I tend to only accept projects that I personally believe in. Once I'm motivated, the only way I stop being so is if suddenly, the person to whom I'm working for, stops caring about the whole thing.

The reason behind this is that, when doing something you love, it lets you work on it for hours and hours without end. It will also make you doubt, which is VERY important as it allows you to question everything you do, which ultimately leads you to improvement.
However, for there to be any improvement, you must be willing to find the answers to your doubts. To find those answers, you must know what questions to make. I tend to unconsciously follow this thought process - what? why? and how?
So, for example: This music passage doesn't sound very good. -> What's the cause of it? -> (identify it) -> why is it not working? -> (reason) -> How can I make it better?-> (solution).
In reality, finding the solution might take somewhere between a second to long hours along with , perhaps, some frustration. But when you do find it, that's when you grow.

This is about improving yourself in order to become better than the person you were when you started on a project.

Don't stop improving!
