Well, when the EV is finished, it would save me money in car costs, so I consider it an investment, I guess.
I'll pay less to go to work/study/family in the future, and be green at the same time.
I really don't wanna discuss my choices in life in this topic, but lets just say others probably conclude I wasted years of my life (and college funding) doing other things, like fixing up my car, helping building a solar powered racing boat, etc.. On the other hand, I think I have some valuable life experience, had lots of fun, and I know what I want and where I want to go now, where I was previously very aimless and unsure of what I wanted carreer-wise and otherwise. Too bad I got kicked out of Mechanical Engineering for not completing 1 math class, or I'd be in my final year already. Oh well.
