work as an independent consultant. same jobs, 5x the pay.
Maybe twice the pay, Id believe that.
Also there can be a secondary multiplier if you have 2 gigs at once. So 5x becomes 10x if you have two.
I don't think most people who do this are interested in going at it this way 252 days a year though but yeah if one's keen to 500k is possible.
I found there are so many parts to running your own business that I am well and truly horrible at, well I went back to working for consulting companies.
