If you aren't using Reddit, you are missing out.
I'd like to share a few of my favourite subreddits. These subreddits are why I love and browse Reddit regularly.
These subreddits are extremely valuable. They always have intellectual conversations and contain amazing members devoted to growing and progressing their lives.
A great way to find the best content of these subreddits is to visit their WIKIs or TOP filtered section.
This is true, it does take a bit of digging to get into this and filter out the dumb stuff - but if you flip it to "Top," like I did in this post here, you'll actually find the helpful/applicable stuff.
