 I don't know where to start with investing and doing it with mental peace because a few years ago I made some money on Tesla, and that was – although it worked out great, I look at it now and it was just a super stressful time, and it almost kind of affected my own relationship, which is – she's amazing now we're getting married. But my question is where do I start with investing, and how do I know how much to put towards paying down my mortgage versus investing versus retirement?
