Buy what you know, don't follow the crowd. Know your limits and don't be afraid to lose a little to win a lot 😉 stay rational when others are anxious and play the long game when you are young.

This has put me in the position to create opportunities to pursue my interests and have a safety net. Thanks Papa, I hope to increase your ROI. ...
