Confidence is a hard goal to aim for because you never really have it until after you initially need it. if you wait until you feel confident to try something you may never get there.
Instead you might try focusing on being courageous.

The (almost) universally prescribed cure for creative flourishing is a creative practice. Whether it’s illustrated journalling, morning pages, a dance or music practice. I recommend this a lot, but I’m here to say that it’s not the only answer. I promise you can unlock your creativity and improve at your craft without rigorous creative practice, productivity habits or even being consistent at all.

I frame my work around creativity in the context of the abundance of nature. If the natural world is so abundant and diverse then it means that you, as part of the natural world are adding to its diversity and subject to its abundance the same as any other creature.

Ok, cool you might say. But what if I don’t live near nature? Do I have to move to the (so-called)Canadian woods or the jungles of Bali to feel this connection?

No. You don’t. And I’ll tell you why.
