Is it too late for me?

Hey everyone, Ive always been interested in music and Ive wanted to make this my living. I like playing guitar so my goal would be to be a guitar tech or lead guitarist. I’m 25 and I feel like its already too late. I don’t need to meet this goal now, but can I still make it? I dropped out of school and work in the music industry on tours. But Im worried starting to improve my guitar now, Im going to be far behind everyone else and never make it. Should I goto trade school to have a steady income or continue to pursue my music goals?
