Where to go from here?

I’ve been working in coding for about 5 years now. Beginning with python then learning html css js etc i've also completed cs50. I even developed games for a bit in unity and unreal engine. I understand that saying my age now will under express those previous things and thats not the intention i have adequate to advanced knowlesge in the subject but anyways i’m currently 14. Ive been working on OverTheWire trying to learn kali linux but im wondering where I should continue after i finish in order to learn kali and pen testing more? Thanks for the knowledge and help in advance.
