Its a good start to get your PPL and then go from there to decide if you want to make yourself a career pilot. Save yourself tens of thousands if you decide its not what you want to do.
This advice. This, this, this.
After you get your PPL, if you still want to fly, then buy a light single which is IR-certified, and earn your Instrument Rating and Commercial Single ticket. Better yet, get a taildragger so you can get a TW endorsement and REALLY learn what the rudder is for - plus it's more fun. WAY more fun.
Build the time, and if you're careful with the plane, you should be able to get most of your money back out of it; the market has traditionally been pretty stable on fixed-gear singles.
Sell airplane. Buy twin. Do Multi-Add on. Then get into business if you want.
Aviation will suck up VAST amounts of time and money. Make sure you do this incrementally and have an escape clause. Remember that ultimately it's INSURANCE COMPANIES, not the FAA, that drives the major stuff in aviation.
I used to want to fly professionally, and then I realized that what I love doing - flying - becomes restrictive when you don't get to fly where you want, when you want. To me, that was more important - the freedom, and I've happily kept it a hobby.
