Nothing in this world can take the place of persistence. Talent will not nothing is more common than unsuccessful people with talent. Genius will not unrewarded genius is almost a proverb. Education will not the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'press on' has solved and always will solve the problems of the human race.
Whether a person feels positive or not is kind of a comment on their personality and of no great interest. You can find positive signs or you can find negative signs. How you evaluate them depends on something that happened in your life recently or something like that. There's no objective way to do it. The important thing is you try to commit yourself to making the positive signs more real. Suppose you felt that there's 99 percent of a probability that human civilization is going to be destroyed in the next hundred years, but one percent chance it won't be, and that one percent offers some opportunities to do something. Well, you commit yourself to that one percent.
