================================================
So here are my tips to become a professional level maker:
Think about it!
Ask yourself questions like Do I really like to do it? or Is it a fun hobby for me? because when I was thinking about what I might success, it helped me become a skilled level maker and people liked my custom levels.
Learn!
This is permanently required for all new students because this is the only source in doing something great. Everyone needs to learn like in school or wondering what to do to install games. Learning is the thing you need the most.
Get Started!
Always show your first piece of artwork (a.k.a level) to the legendary level makers and ask them if it's good because that's also the way to progress in to becoming a better level maker since they know mostly everything about QuArK or Constructor and they will give you tips and information you need from them. Unfortunately, I didn't do that and I had a hard time progressing in level making so make sure you follow this!
Practice!
Apparently, this is the permanently required too for new students. This helps the beginner level maker get familiar with level making and excels it.
And finally, last but not least,
Don't Give Up!
Sometimes, you try making a level and it has errors. This either makes you get angry, exhausted or sad but remember this, if you leave it, it ain't coming back. Nike's motto simply says, JUST DO IT! because it's just there, waiting for you to do something and wants you to be better and better.

This now ends my tips and tricks guide into becoming a better level maker. I hope it helped you.
