I'm an entrepreneur myself and agree totally with what you mentioned above!
The best part you left for last! "Save part of your profits" - This is so important, because you newer know in business when the good times will stop and the bad times are upon you. Then you need the profits to help your business out!
Even if it is a good time for a long period, those profits saved up can be used to expand your business!
Always have cash stashed away that only you as the business owner knows about! Fewer people know about it the less will want to use it!
Hope your readers/followers head your advice!
Keep on steeming...
