Should we still aspire to do great things?

I’ve been watching and learning and taking in as much as I can from Tolle’s teachings. Often, I find myself wondering whether aspirations and goals are still worthwhile, considering they are not representative of who we are (as in consciousness). I’m not sure if I missed the point somewhere, or if I’m just getting too into my thoughts about this. The awareness that “I am” is profound, but how de we operate in a world that still succumbs to ego in almost everything we do? I would love some insight on this. Thanks!
