I personally find Valheim to be a frustrating game to play solo, since there is so much chore work like constant tree cutting for just one person (the workload is minimized when you have multiple people using their boss powers one after another to improve wood cutting speed).

My advice relates to the pickaxes. The first pickaxe in the game you acquire, the antler pickaxe, is repairable at a standard workbench. Every other pickaxe must be repaired at a forge. So if you are setting up a mining operation at a giant ore vein some distance from your house (you'll be doing this starting in the second biome), it might be a good idea to use an antler pickaxe for this instead of a metal one, since you can easily set up a workbench next to your operation and repair your pickaxe without having to travel home. Even though it's slower at mining, the fact that you can repair it in seconds and keep working saves a lot of time in the long run.

Other tips: Rotate your chests sideways and use half foundations as dividers, you can cram them in four to a wall. Different weapons are effective at different points in the game because the enemies that are vulnerable to X type may be more or less common in a different biome. If you find a surtling geyser in the swamp, you can mine out the ground under it to expose it to water, then it's a free coal/core generator. Have a specific spot in your home where the comfort level is high (basically just put lots of decor close to that specific place) so that you can sit there for a few seconds and get the Rested buff for a long period of time; come back to this spot as soon as the Rested buff expires because it is not worth even attempting to do anything if you aren't Rested. Don't break berry bushes, mark them on the map and come back for more berries later. If you find an old randomly generated building, you can put down a workbench near it and then tear the whole things down with your hammer middle click easily. And if you are building fortification for your base, it's hard to beat a moat.
