A beta must go through a metamorphosis to become an Alpha. The following is a poem by Kendrick Lamar that perfectly describes this process if you substitute caterpillar with beta and butterfly with alpha.

"The caterpillar is a prisoner to the streets that conceived it.

Its only job is to eat or consume everything around it, in order to protect itself from this mad city

While consuming its environment the caterpillar begins to notice ways to survive

One thing it noticed is how much the world shuns him, but praises the butterfly

The butterfly represents the talent, the thoughtfulness, and the beauty within the caterpillar

But having a harsh outlook on life the caterpillar sees the butterfly as weak

And figures out a way to pimp it to his own benefits

Already surrounded by this mad city

The caterpillar goes to work on the cocoon which institutionalizes him

He can no longer see past his own thoughts

He’s trapped

When trapped inside these walls certain ideas start to take roots

Such as going home, and bringing back new concepts to this mad city

The result?

Wings begin to emerge, breaking the cycle of feeling stagnant

Finally free, the butterfly sheds light on situations

That the caterpillar never considered, ending the eternal struggle

Although the butterfly and caterpillar are completely different

They are one and the same"
