Does length matter?

I have been contemplating about this for a long time now. Back then, I’ve been comfortable with its length. But now, I’m not sure. I've been thinking and I have narrowed it down into 3 options: 1. just wait until it grows 2. use substances to "speed up" its growth or 3. just let it be, which is short in my case. But does it really matter if it's short or long? I've asked around about it, some say it's better if it is long, others say short, some say it doesn't matter as long as u can carry it and you're comfortable with it. Hay... it is hard to decide. My clipper will have to wait a little longer on my verdict.
