A wage is good in that it gives you regular income, but it may just never increase much. You need to the guy who invested a few thousand in a memecoin and is not a billionaire!
Self-sufficiency is useful to reduce your dependence on wages. Paying someone else to fix things soon gets expensive. I've done so much DIY over the years that I am more willing to pay others to do it now.
I did just sell a little Polydoge for quite a healthy profit as it goes! Not billions, but a tidy amount.
DIY is hard work and inefficient, but it does save you fiat!
I've learned the best thing to do is find a professional that doesn't mind you working alongside them, then you can learn as you go and benefit from their efficiency too.
