There's a saying out there that nothing is impossible if we just try hard. This may be a bit exaggerated, but the point remains - things are often more possible than they seem, if you really believe in them and work at them.
But on the flip side, there's also a path to certain failure, and that is having a self defeating attitude. You may not even realise that you have one. You may call it 'being realistic'. But that's no excuse - who knows what really is realistic or not without having tried and persisted?

So don't 'be realistic'. Be hopeful, and try very, very hard at life. You may be amazed at the results.
