Best advice I can give is this: Be patient. The game is not something you should be rushing through and expecting smooth sailing (pardon the pun). Setting challenges for yourself is a great way to explore how things work but insisting that everything works the way you want it to? Not so good. You have to learn how things actually work... not how you want them to.

Take your time and learn the areas and their inhabitants. Every biome is different and full of surprises... most of them unpleasant, until you get yourself geared up properly and work out the various mob's strengths and weaknesses. It gets grindy but there really is no way to rush any of it successfully.

When you find yourself wanting to smash things...? Take a break, recoup and try again later.
Losing your temper means that a silly, meaningless game that is meant to be entertaining has way, way too much power over you. Mastering anything starts with mastering yourself.
