At the core of what constitutes being a Satanist we find deep, unyielding, all consuming love for one’s self. Unless you love yourself, you cannot be called a Satanist.
Your love for your own being must not depend on how well you did in the world so far; or comparison to some other human beings, or on assumuption ‘if others like me, then I must be likeable’. It must be unconditional.
Such love will actually lead to doing very well in the world; to comparing favorably to others; to being liked for who you are.
Don’t be a Christian. Be happy with yourself.
