hitmeister
Someone who only wants a hit and won't get a regular job or prioritize a career, even though they don't have money to live well enough or save for the future.
Ernie refused to start entry level because he was a hitmeister and wanted to be rich, so he kept starting podcasts, writing movie scripts, and writing up fake dog operations on Go Fund Me, but eventually he got rickets from scurvy, his skin sagged and his hair got thin due to lack of protein.
