TIP#27: Purge your Wallet

Purge your Wallet.! Your name it is not George Constanza. (If you don’t get the reference, please google it, it is worth it)
What do you really need? What do you have? The problem with wallets is that things crawl there and never leave. You have that number that you don’t have a clue what it is for. The 2001 Insurance Card. The Gym Membership Card. (you know the gym you cancel the membership four months ago)
Anything in your wallet that you don’t use, should be out of there. Check it often, purge it often.
