You are already given loads of good advices from various points of view, if I may pitch in my 2 cents, try to experiment, get yourself accustomed to, and learn to use and care for the right equipments.
i.e. all the different knives are designed to special purposes, learn the differences and how to use them, as well as maintaining them in the best condition possible. Using the right knife will make your life a whole lot easier, and actually safer.
Also if you are accustomed to just using a nonstick skillet, try to learn cooking with different types of vessels like cast iron, SS, Copper etc. and see what kind of effect they can attain.
Don't be afraid to try new gadget, mixers, robots, food processors, slicers for just a few example, but before you jump in, read the manual and make sure you will know what you are doing, and the correct usage.
This practice will enhance your world of cooking so much.
