You have lots of drive right now, but are you letting it steer you into stressful places? It's all well and good to be aggressive, but you have to be mindful of the fact that failure is always possible. It's not that you should think negatively; it's just that you need to practice balanced optimism, so have a backup plan. Just because you want something does not mean you are going to get it. Big lessons come from even bigger losses.
