Unless you already have more money than you will ever need for the rest of your life, you need a pension – and it’s the same for everyone else. How else will you fund your life when you’re not working anymore?
You cannot avoid being old one day – but you can avoid being old and poor. Get yourself a good pension plan and make sure you have enough money to enjoy a nice retirement, nomad-er where you end up! Future You will thank you for it :-)
