How old are you? If under 25 I'm going to literally hunt you down so I can punch you in the face.
Too old to learn an instrument
>when you look around at your peers
This isn't going to help. Worry about improving your own shit. Be stronger/healthier/more skilful than who you were yesterday and look forward to improving again tomorrow. After a while, you're not going to give a shit about how well your peers are doing. You might even start surpassing many of the complacent ones in a matter of years or even months, but who gives a shit anyway?
Are there ANY famous musicians who didn't start when they were kids? I'm only 20 and I still sometimes fucking feel like I'm starting too late and have already missed my chance.
you could probably learn to make some decent shit in FL studio in like 2 days of dedicated learning
