Well,
The OP doesn't sponge off Mum & Dad, is passionate about music, seems to have earned more than the year before for each of the last 3 years and is only 24.
Go for it mate.
I didn't, but I don't regret it. Started playing live at 15 / 16. Had my own business since age 26. That paid the bills but also allowed me to use playing as a release from the work pressure and indulge my gear fetishes.
Had a few good and big gigs in the early years and that was enough to look back on and nostalge. That has suited me but everyone is different.
If it's your ambition, and you seem to be realising it, do it. Lots of people will offer advice, some good, some bad, but the bottom line is that it's only you that will regret not going for it.
Best of luck with whatever you decide for the future.
