Ways to improve at minecraft?

If you mean be a better builder, there are various things you can do, one you can look at other peoples builds. Don't still the building just take some ideas and make them into your own. You can also start experimenting with blocks to find out what you think looks good and how you can improve something else. There are lots of ways to improve your building skills you just have to look. If it's at surviving I would just recommend building inside caves for the beginning of the world and mine as much as you can until you have decent armor to explore the world and not die.
