I would stress the importance of maintaining a high savings rate, jump starting my savings account, and investing in dividend stocks as early as possible. Let the power of compounding get as early of a start as possible.
Also, I would tell myself to resist the urge of lifestyle creep now that I received a full time job offer and a new cash flow. It’s the best way to keep your expenses down. Live frugally and again, invest as early as possible!!
Thanks for the fun topic.
