My friend helped me become a better friend

Me and my best friend have been friends since the start of 2024. We have grown really close together, we play games a lot and hang out a lot. We have the same interest and we're just really good buddies. We usually always harass each other (not literally just kinda playfully ig) And we never really are serious towards each other. And I have dreams of becoming a streamer and usually he cooks me for it in a joking way, but recently he didn't joke, he genuinely said "I believe you can do it." And bro that was the best feeling I had in my life. the feeling of knowing your best friend believe in you is so great. And now that I know how it feels, I'm starting to do the same thing, and believing in my friend that he can accomplish his dreams. Idk why I'm ranting about this, but yeah.
