I feel like a very good piece of advice I got that is worth sharing is that for every decision you make you need to ask yourself three questions. Is it legal? Is it smart? Is it safe? If the answer to one of those is no then that should raise a red flag for further investigation and if you answer no to two or more of those then you really need to pump the brakes and take action to find ways to change those answers to Yes or just don't go fly.
