How to play Minecraft and not die?

Hello! I have encountered a problem in Minecraft – I keep dying constantly and can’t figure out how to avoid it. Every time I try to explore the world or fight monsters, I die unsuccessfully and lose my resources. This is starting to annoy me a lot and I need help. I understand that I should use different strategies and techniques, but I still can’t survive in the game for long. Please, can you give me some advice on how to play Minecraft and not die constantly? I really want to enjoy this game, but constant deaths are ruining my gaming experience.
