Keep your guard up so you can protect yourself

You have to look out for yourself because you can't count on anyone else to. It's easy to assume that those around you want what's best for you. But the truth is they will always do what is best for themselves. You can't blame them. So if you don't protect yourself, you have no one to blame but yourself. You have to look out for your best interest not be so niave to get caught in the end unable to stand on your own. You will have many adventures throughout your life with others. But the path you choose on your journey is the path that is best for you in the long run. It's not being selfish, it's being smart enough to know that you have to protect yourself from whatever life may throw at you. Your future will always be the results of what you did yesterday.
