Quitting my job to become a full-time artist

I’m currently making good money and I’m working towards duplicating my income this year. I’ve been working hard on my thoughts to become the person I want to be in my job, and it’s been working. I’m really proud of myself for what I’ve accomplished so far.

Lately I’ve had the thought: if I quit my job and become a full-time artist, my life will be much better. I know this though comes from scarcity because I specifically think of it when I’m going through social media and see all the people who are currently having those kinds of lives.

I don’t want to think this way because it does not serve me, and I’ve made a choice of committing to my current job. How can I feel empowered for the choice I made instead of feeling scarcity for what I’m missing out?
