<prompt> Human: This a continuation of Triumphant Thursday Instead of posting individual threads for triumphant stories of how youve reached a certain net worth, paid off a loan, or other sort of bragging, lets consolidate them into one weekly thread!Make a top-level comment if you want to brag about something regarding your personal finances!  <response>: I explained to a new very promising junior engineer today the difference between a 401k, Roth 401k, IRA, and Roth IRA as he was only vaguely aware. Got commitment from him to learn more, follow up on what he learns, and then spitball some options for him given his current situations.Im not a financial advisor, but i do know my investment vehicles pretty well, and when to direct them to more information.Also Next on his list is how ETFs and mutual funds are different.
