This is something I often encourage students to practise because it changes the way they experience English. Once you stop expecting yourself to understand one hundred percent of everything, listening becomes less stressful and reading becomes much more enjoyable.

Another useful habit is to give yourself a few seconds before reaching for a dictionary or translator. If you immediately look up every unfamiliar word, your brain never really gets the chance to work with the context on its own. Try finishing the sentence or paragraph first and see whether the meaning becomes clearer. Even if your guess is not completely accurate, you are practising an important skill: understanding English without depending on a translation every time something unfamiliar appears.

It also prepares you for real conversations. There will always be unfamiliar words, different accents, expressions you have never heard before, or moments when you simply do not catch what someone said. Being able to stay in the conversation despite that is an important part of becoming a confident English speaker.

As your English improves, you will naturally understand more and more. The interesting part is that some of that vocabulary will become familiar without you ever sitting down and deliberately memorising it. You will hear the same word in different situations, gradually understand what it means, and eventually start using it yourself.
