Biggest dilemma of my life thus far

I’m in what could be called the biggest dilemma of my life thus far (30F). I’ve had a beautiful life filled with so much adventure and rare opportunities and I’m so incredibly thankful for that. One thing I feel eludes me as a person has been creating the financial stability I deeply need to be able to support myself and get out of feel like I’m a character in Mario jumping brick to brick when it comes to money despite being hardworking and unwavering about trying to build a career. Within the past 5 years I have built a tiny home out of a 30ft school bus in Hawaii. My intention was to have a space to live as rent out here can be astronomical, and my deeper intent was to motivate myself to learn how to tattoo and have this be my own personal studio one day. I just finished a year long apprenticeship, I also live in an apartment now and am at this huge crossroads of fallowing my head or my heart. I have the opportunity to sell my bus and make around 30k back. That would be enough to pay off my debts, have some savings and also invest in other financial persuits. Or I could go with my heart, find a way to finish the last of my build and invest in the equipment I need to have this a fully functional studio and do something no one has done on island before. I have been going over these options for years and have thought of everything in between. Would love to hear everyone’s view point as I’m dead set in the middle of what to do.
