€ 1 million is a lot of money, but it's not enough for a lifetime to relax on.... Even if you put it in the bank, you're only looking at an interest payoff of like €20,000 a year. Add inflation over the next several decades of life....
You can survive on it, but you won't be living an upper class life with lots of traveling and all...
20.000 to 50.000€ in interest/yield from investments a year would be totally enough for me. I only need about 900€ right now for monthly payments, so I could spend the rest on travel from the interest alone - without even tapping the 1 million of capital still in the bank.
