I'm 15 and want to be a hazmat truck driver and need to know every step?

I know that I need a CDL, tankers endorsement and when I'm 21 I need hazmat endorsement so is this a good plan, I start studying at 17 to pass my CDL and tankers endorsement while I already have a small job just for invome then once I turn 18 I go to the DMV to actually pass these tests and then once I have those I get a job as a non hazardous materials transporter like milk and water for example then keep that job until I am 21 and can pass the hazardous materials endorsement test and finally apply for any kind of hazmat transportation where I would be a paid apprentice and have the perfect job making a pretty good amount of money which is the ultimate goal (starting wages 60-70k after experience anywhere from 100-180k)
