When you realize something will be difficult, that is a good thing. That means everybody else will give up before they start.
If you’re the person willing to start and give it a try, you might just succeed.
Doing difficult things is valuable because the difficulty of them means few people do them. But the most valuable things you will do for yourself and offer to the world around you will often be those difficult things that others aren’t willing to do.
It’s difficult and that’s a good thing for you.
