Thanks for sharing Aja! And congratulations. It sounds like you’ve done amazingly well for yourself.
What might help you a great deal (as it did me) is automated savings, which pushed me save for specific, tangible goals in the future like a wedding, property, or travel (rather than just saving a lump sum for some vague goal).
Ramit’s book I Will Teach You to Be Rich was a really great help for that, an has a specific section talking about freelancing/irregular income and how to structure it that you might be interested in.
Another thing that I’ve found successful for myself is purchasing rental property for the purposes of generating semi-passive income. Maybe that’ll be a good avenue to invest.
