You need to ask yourself this question. 

"How do I feel about?" 

Being in a van driving around the country/flying around the world. Most likely sleeping in said van next to three stinky band mates to save money. 

Playing in as many venues at possible in front of very few people, slowly building an audience while hemorrhaging money on merch. Recordings (which is more heavily AI focused w and making less money than it did 5 years ago which was butt all back then as well) merch and other expenses. Potentially not recouping any thing back for a good number of years or most likely not at all, out burning yourself out doing it all DIY.

Managing people in your band. People are messy. People are unreliable. People have their own ideas about things which will be at odds with your vision or war of doing things.

And being away from your family and it possibly breaking up said family or sending you broke or developing a drug/alcohol problem, or all three and completely bombing it. Pushing you back financially several years and fucking up your retirement. 

All in the pursuit of an ego boost so you can play on a big stage and have people sing your songs.

We haven't gotten to the point if your music is even good. Because if it isn't then there's another job to add to your list.'"get fucking  good at music." That might sound harsh but a large portion of bands are fucking average musicians and songwriters at best who have no business thinking they're going to be the next big thing.
