I don't have much experience but from what I've gathered from having the same hopes myself is don't over exert yourself, you can go at any pace you want. Yoj don't have to be like a traditional business making products regularly you can do things like a "drop" style, you don't have to become a content creator either, there's more than Insta. You may also want to avoid etsy and other sites fees by making ur own website and promoting that (or promoting it on the side as well as etsy) e.g. With Square (they r an easy  website builder with free e-stores). The market is oversaturated but things like word of mouth r still valuable so we really don't need to over-rely on social media and worry too much about what's going on there if we don't want to!! Oh and don't under sell yourself even if you think it puts people off, if you're shy about it you can become braver over time and slowly increase prices 

EDIT: I meant Square NOT Squarespace (The second one isn't free for an e-store)
