Relying on yourself is better than relying on friends,
I do agree that we should all learn how to be independent and do things on our own without the help of others however I also think that sometimes it is even better to ask for help from people that genuinely care about you. You will find soon enough that you cannot do everything by yourself.
of course we also have to be smart in choosing friends, because many of them are double-faced.
Surrounding ourselves with toxic people will make our life a living hell. No man is an island but we should choose carefully who we want to be on that island with.
