There's no one way to do things.
There are many paths to a destination.
Keep trying until you find the path that works for you.
The paths others have taken may or may not be the right one for you.
They can teach you what worked for them and what to avoid. They can help you increase your chances of success. But, they can never guarantee your success. (Learn from them anyway. Experience is a valuable commodity that others have.)
When a path doesn't work for you, it doesn't mean you're a failure. You just need to try another path.
Don't be fixated on a single path. Focus on your destination, but don't obsess over a single path. If necessary, take a step back, zoom out, and try to see other paths around you. There are plenty of other paths out there. You just have to turn your eyes away from the path you're on.
Keep on trying different paths. You'll get to your destination. But, if you give up, it's already guaranteed that you won't reach it. It's the only way to fail.
