I will always support the idea that creative people should make digital products to sell on stocks apart from their main job. The main job is not always stable due to different reasons.

Moreover, it doesn’t take much time to make a digital product for stocks so you will always have time for yourself and your family, And if your products start selling well, you can make stock sales your main income. You won’t need to work somebody, you’ll be able to work for yourself wherever you wish. The only thing you need is Internet access!
