If you don't act like you're slightly delusional, you stand out as a minority. You mean mentally ill -- depressed. Being an entrepreneur seems like the opposite of being depressed: extremely overoptimistic vs. overrealistic (depressed people are less overoptimistic than non-depressed people) emotionally resilient vs. easily emotionally drained able to derive satisfaction from drudgery that will (probably) not pay off vs. unable to derive satisfaction from rewarding, constructive, fun activities feelings of self-worth unaffected by failure vs. feelings of self-worth unaffected by success
