To get mining higher mine at pits such as the one in Osyla that gives aluminium ore. So once that give rocks.
To get fishing higher just sit down and fish.
To get collection skill higher vaccuum at pits like the one in north island that gives you clay or pits that give sea water or even at grass bushes.
To raise the cutting skill vaccuum at wood piles like the one by the tree where you find Niss.
