I'm Worried About My Future

I don't see how people work for 40 years for a company, spending a 3rd of their day working for someone, for majority of their life. Then retire and die a few years later.

I think about what I could do to make money for myself. 27 and already tired of punching the clock. Gots so much else i want to do and i dont have the energy for it after work. Sad sad life
