It's a no win situation when we compare earnings
Dave is a very high earner by being " smart " but he is also meticulous in his operation. Most in this business are relatively happy to earn what they do, although some would like to earn more,
To increase your income, requires " change " you have to change what you're doing, maybe just a little change, but if you do the same thing as you did, last year, you won't increase your personal wealth.
I was pro rata, probably earning more than Dave 25 years ago..............but...............not from the sweat of my own brow, there were several others working for me and I benefitted.
Today, I do very little in this business, but could survive on the little I do, but I have another business, which employs around 16 people and collectively turns over, a little over £300k.
This business was started nearly 7 years ago, to provide work for two relatives and to provide funds for another venture. I have just appointed RTA ( they have 14 pages in Daltons Weekly ) as our selling agents...................the business should raise approx' £250k.
That is what you should be building a business for...................to sell it !
