Wanting to be a Owner Operator after CDL School

I am a 60 y/o that's tired of working outdoors, enjoys driving. I am thinking of getting a Class A CDL, then buy a used truck, get insurance and begin hauling loads long distance.
1.) Will I be able to find work easily?
2.) Will insurance be too high for me to make any money, being new to trucking?
3.) Is it best for me to work for a company first and for how long?
4.) Would I need to buy or rent a trailer or flatbed?
Thanks

 

So how long would it benefit me to work for someone else. At my age I also worry about getting a job too

 

I am interested in profits, if it is profitable.

 

Good advice.

 

I would think that insurance might make it impossible to make a profit just getting started, because I would be driving a truck without much experience. Don't know much about the taxes either. This is something I am now looking into. Good to hear realistic feedback, instead of planning a pipedream however
