If you haven’t figured it out yet problems are going to happen.
Nothing goes as planned.
Be ready for it.
Learn to see them before they fully materialize.
...but most importantly pay close attention when they arise, because it will show you who the winners are and who the losers are.
Losers argue over "whose fault it is".
Winners just fix the problem.
It's that simple.
Be a problem solver.
Surround yourself with problem solvers.
The rest will take care of itself.
