I bet you know what I'm trying to convey. Yes, I mean you can try to express the same idea in English with a different way, instead of the way that you may think is the only natural or right way.
For example, you can use 'amazing', 'excellent', 'fantastic', 'terrific', 'well down' or 'good job', instead of 'good' or 'nice'. You can say 'an extremely hot day' instead of 'a sweltering day' if you can't remember the word 'sweltering', which is what you really want to use.
It can be so monotonous, dull or boring to use the same thing all the time - that is to say, you should try to change from time to time when you are writing or speaking. You can use another word, sentence structure, expression or a synonym instead - don't repeat the same one again and again.
The thing (or the problem) is, you are not always so sure if an expression is as natural or acceptable as the one you are familiar with. You may tend to use what is said or used by native English speakers - you may think it's safe to do that.
You have to risk making mistakes, though, because you can't make sure every sentence you made is natural. Chances are, you've been helping create sentences or exprssions that are never used by native speakers - you should try to make sentences that are at least grammatically correct when in doubt.
Be creative or confident - try to express whatever you're trying to say the way that comes to mind.
