I like the approach. Work lives are uncertain, as are growth paths; some MMM effort could revolutionize your freedom level over the next 5-10 years. Repeated small steps are very powerful.
Start here:

1. Set up Mint, track your current expenses.
2. If you're not saving 50% of after tax pay, figure out how to do so.
3. Regardless of situation, make a game out of maximizing joy and cutting expenses in your 3 to 5 biggest cost areas.
4. Include taxes as one of the areas to maximize.
5. Start by researching a particular area, then make relevant moves.
6. Include cooking as a skill to practice.
7. One option is to practice mechanical skills such as home repair and car maintenance.
8. Look up house hacking and see if there are relevant strategies. Depending on where you live, maybe find special situations of cheap rent, rather than buy. Look for roommates/homeowners who will give a price break in return for the privilege of living with the musically talented?
9. Learn about investing. Read:

In opposition to the "all stocks" philosophy, review portfoliocharts.com by learning all of the investment terms, and finding three investment portfolios there which have higher returns and lower drawdowns than all-stock portfolio. Be sure to do this exercise for more than one country; the results vary by country.

https://www.bogleheads.org/, read the "Start Here" section, and get advice about how a portfolio with less stock could have a higher return than one with more stock.
10. Write yourself a personal investing plan and follow it. Use Google if 9 above hasn't fully equipped you for this task. Remember that where MMM has a thriving community based on the best thrift/life balance, Bogleheads specializes in the best detailed tactics for maximizing investment. Just ignore their income standards and most of their consumer spending remarks. :)
Whatever you do, keep up the gratitude. And look for ways to share the joy with others. I love the track you're on.
