By all means build online. But please for the love of Christ, do something interesting with your new hard earned gains.
Write and produce a short film, buy a 35mm camera and randomly head out to Asia, pick up an old Land Rover and bum around some African countries whilst working out how you can give back.
It will do more for your mind, creativity and ambition than sitting in the Royal Palm in Dubai with your personalised Rimowa looking at your tacky ceramic Rolex.
Not to mention the stories that will inspire your kids in years to come.
You get just one shot at this, why not be unique?
