Quit trying to become a master of everything.
It will only result in a lot of lost time and money.
Think of it this way...
You can spend days learning how to fix the engine in your car...
Or you can bring it to a technician that specializes in that engine, pay them to fix it, and get back on the road in a fraction of the time.
Now, instead of wasting a bunch of time learning a skill that will be virtually useless to you in the future...
You can put your focus and effort toward things that you are actually great at.
You don't have to know how to do everything when you can surround yourself with people who have the answers and skills that you don't.
Spend time on what you do best...
It's a much better strategy to achieve the most, and make the biggest impact possible.
