Brother, let me be honest with you. Not all is as it appears.
Since the new Medium changes kicked in, most of the top writers' earning have gone to the dumpster fire. I witnessed a 70% nosedive in my earnings - exactly the month after I quit my full time job - so a 1/10th or higher fall in earnings in total.
So, like you're beginning now again - Medium itself is beginning again. We're all "Re-learning" the new system brother.
And the digital products you see? They're all free lead magnets (upgraded several times I grant it) - only one paid product so far.
Not saying all this to say I've done nothing in the last year - or moved ahead of where I was. I ofc have - but growth happens in different time frames in different ways for different people.
No reason to feel FOMO - you got this. We're all new in the new Medium system.
I am learning as much as you are brother. Peace!
