Now I'm not of the view people shouldn't try to change the world but why should that be fixated on a business, why not a community effort, why not research, why not charity based, they all provide you with a range of skills. We have got a saturation of those starting businesses in every industry (especially mine which is quantum computing) and most have a poor idea or a repetitive idea or an idea that so unthought out it can't go anywhere.
(I will say less should go backpacking. Travelling on the whole now has become a distraction from life instead of a discovery. You are better taking that year or 6 months and spending it on something you love to do. That will show you who you are more than visiting some of the poorest nations on earth.)
