Look at the positives
The future is always unclear. But what is always clear is the moment. You can look at everything around you and know that it is there, and in that moment it isn't going any place else. So why not enjoy it? Plan for the future, set goals, and make smart decisions, then balance that with living in the moment. Nobody knows what tomorrow is going to bring, so why not enjoy the now. The future is going to happen one way or the other, and until then we may as well enjoy the good things in our lives.
