Why am I destined to have the number 4?

I think it's because you happened to have a lot of contact with 4 when something important happened, but you should have paid attention to it before you found that there was no necessary connection. If you pay more attention to it, you may find that numbers are everywhere, and the probability of each number appearing is similar. But if it won't affect your life, it's good to have a spiritual sustenance, because sometimes I like to associate some numbers with my fortune, hehe!
