Is anyone investing and not tracking their money in general/budgeting?

I was wondering if you or someone you know is investing money without having healthy money habits? I believe it's kinda requirement to be somehow financially literate and track your income, expenses and do budgeting before you even think about investing. However my friend don't think so and wants to just passively send either fixed amount or salary percentage without thinking about finances. What are your thoughts and philosophy around this? link
