Welcome to the steemit community. Your introduction post was extremely well put together so great job there. If you continue to post that well I have no doubt you will do great here. Some little pointers to help you out on your steemit journey.
With your account you will see you have a set of keys, we call them permissions. Only log in on your posting key and never on your owner key. The owner key or master password is the one given to you when you first opened the account. The active key is for financial transactions only and the master password/key is for account recovery. By logging in only on your posting key you keep your account secure. Best of luck and keep up the great posts. If you have any questions don’t hesitate to reach out. Keep steaming. :)
