Take your time and have fun with it. Get your own opinion of the game. Don't try to get everything all at once. If you need someone to run with, just ask. Cheers
Don't die, don't infuse anything until you're 265+, hold off on your Exotic Quests until you are 265, and use the Destiny Item Manager Google Chrome Extension to help you figure out which weapons to hold onto, which ones to scrap, and to manage your inventory/vault. Also, hold off on doing milestones that reward powerful engrams until you are 265+
