17. It's stupid to sit on money. You need money to get freedom - from what you don't like to do or it turns out badly. And freedom is needed to do what you do well, and you are ready to do your best for free. I regret that after the appearance of the telegram channel, I invested too little money in advertising, but waited for it to grow on its own (although there was money; it was just a pity). And now promotion in the cart has become so expensive (a real subscriber = 300 rubles) that there is no point anymore. By the way, the last investment in the promo was one of the failures of last year - a million rubles went nowhere.
