And from here we could start speaking on how are you going to save regularly, if it is going to be 10% of your income, or 5% or 50%, how are you going to learn about investing, etc...
I was lucky to start investing when I lived with my parents, so they provided for me. Although I didn’t have constant incomes, at least I didn’t have to pay for bills, so it was the best time to invest even small savings. And personally I find the strategy of investing 10% quite reasonable. As you don’t feel a lack of money and you invest something in any case.
