My son just started a new job around 6 weeks ago. He didn't use his bank account for 5 or 6 weeks so he didn't check the balance or look at his statements. Big mistake. He was overdrawn by £1.27. He incurred bank charges of fifty pounds. He didn't notice and incurred another £70. Ouch.
Today he said that he has learnt a lot from this. He will check his balance daily, he will always open his statements when they arrive. If he really does learn from this then it is actually £120 well spent. He added a couple more rules of his own. No credit card ever. No loans except for appreciating assets or higher education. If you cant afford then you can't have it.
I told him to add a couple of extras; pension planning and investments.
I am delighted with this result.
