Difficulty is the Barrier
Difficulty is merely the barrier that separates people that do from the people that want.
We can want a lot in life. A guarantee is that there will be difficulty; we are going to be challenged. When we want to accomplish something professionally, personally, or we want to grow, there will be difficulty.
The difference between those that do and want is how they manage difficult situations: how they get through it or how they get past barriers. It's a barrier, it's not a stopping point. It's just a hurdle. You either go around, you go over, you go under, you go through.
Those are your options. Understand that a barrier is going to make the effort worthwhile. It will make you stronger.
Difficulty is just the barrier that separates the ones that do, compared to the ones that want.
