How My friend (Entrepreneur) making 70k per month interesting story?

Daily I'm going to gym one day i met one businessman he has very expensive car in parking. I asked him what do you do for living he said i own businesses and real estate rest off, and i was like it's okay then after two days I'm uploading my designs on redbubble site & then he saw me that businessman asked me what are you doing men I said I'm uploading design on tshirt,mug,& some other products and i get 30% profit margin when it sold. And that time i was making around 100$ per month and some days passed, me and that businessman never met for 1week and after 1week we met again and i saw that businessman he was opening redbubble site and he has 50k $ in there account and i asked him how do you able to make this much amount of money then he said, Bro when you told me about this business (print on demand) I researched and hire some employee and paid him to design and upload 60design per day if see is it works and then in first month i made 2000 grand and then grow 2000k $ to 70k $ per month, And then guys I just shocked he took that information very seriously and made 70k per month and from that day I feel like we can do everything in life but we just want to do it first lot of people just overthink and do nothing so i hope guys you will take some inspiration from this story.
