Studies have shown people at the workplace are only productive about 50% of the time, so that would be 4 productive hours in a typical 8 hour work day.
Some companies are even moving to 4 day weeks, or giving employees "unlimited" vacation time.
When you are an entrepreneur and have control over what work you do, you have a huge advantage.
You get to identify HIGH LEVERAGE activities, the ones that will really move the needle...
And focus your work hours on those activities.
Because of that, you can make a big difference in a very SHORT period of time...
Meaning you can work a lot less hours overall and achieve the same (or better) result than you can at a job.
This is why, for my friends who want to make the leap to entrepreneurship, I say DO IT.
Don't put your family at risk, but carve out at least 30 minutes a day to start chipping away at your business.
One day...that business will actually become something that can provide for you, and you'll be able to do it full time!
It won't be easy, but it WILL be worth it.
(P.S. - Make sure it's based upon your passions, not just a money grab, or you won't persist when the going gets rough, which it will!)
