Sure! As long as your job isn’t your only hustle.
Your job, your employer, your boss is only providing you one income stream. Just one.
You cannot build wealth with one income stream. You cannot build financial security with one income stream. You can no longer retire as comfortably (or at all) as you would like with one income stream.
Yes, you can hustle at your job. Get that employee of the month award. Get that promotion and raise. Just make sure when you come home you’re writing, or blogging or building your YouTube brand. Maybe you’re into website building, graphic design, or preparing taxes. Just don’t sleep on yourself. You’re worth more than any W-4.
