There's an interesting subreddit on Reddit which is full of good tips and tricks. I am going to share the top 10 for the last 24 hours. If this post is well-received, I will do it more often :)
1. If you walk your dog when it's hot out, make sure to allow your dog to walk on the grass or something else that's not too hot. If you can't walk on it barefoot, neither can your dog.
2. When Googling a topic, include "site:edu" to get more accurate resources
3. If you're working on/have an idea for a startup, describe it to people as a "personal project", and focus more on your passion for its purpose, opposed to the monetary aspect of it. They'll be more interested, and you'll sound like less of a pretentious douche.
4. If you're turned down for a job, ask the hiring manager if there are any pointers/advice they can give you for the future.
5. If you have a bunch of loose dimes and nickels in your pocket you can put them into a vending machine, then hit cancel and it should give you some nice quarters in exchange.
6. When cutting up a check or debit card throw the pieces in different garbage bags on different trash days
7. On most DVDs pressing stop, stop, then play will skip the trailers and start the movie immediately
8. If you're a plus-sized woman, always wear a tank top under your shirt. Your clothes will fit better, and any gaps in clothing (shirt is too short, buttons pull) will be masked.
9. If you ever drop anything small on the ground, stay completely still and only move your eyes.
10. Whenever purchasing online, do a quick Google "[website name] promo code"...you'll often find a working code that will save a few percent, which really adds up.
