What is a good way to start practicing an hobby?
To me it’s “having fun”. I’d use these words because we can’t expect to do something if we don’t enjoy it.

At the very least, this is a requirement.
It’s strange to note that we all overthink too much. Maybe we dream and imaging the future, we imaging how we could make money out of it and so on. And that is the thing that makes it tough, because if reality doesn’t match your expectation you’re bound to be disappointed.

Starting small is also a good thing. Starting easy, with less rules than the ones required.
This way you can learn gradually and improve step by step.

Anything more than that and you risk to put too much pressure on the task and on you, risking your entire passion for something.
