It’s easier NOT to challenge. It’s easier to go along with the way it’s always done. At least you can say it’s ‘tried and true’ – even if it doesn’t work. If you try something new, or different, or radical and it doesn’t work, who’s to blame?
It’s easier to play safe, to NOT take risks and to be the person everyone expects you to be. It unsettles people when they see another side to you.
It’s easier, but is it what you want to do?
