Is anyone else terrified of this?

God damn I am so scared. I am SO scared of waking up in 40/50 years and thinking to myself I have wasted my life away.

I am only 20, I have dreams I want to meet. They aren't anything grand like getting rich or famous. I still want to be happy. Look at what I have done with my life and be okay with that. I hate the feeling of regret. I do not want to experience it ever, not to that extent especially.
