<prompt> Human: My boss wrote a blog post where he gives 10 financial lessons for his 18 year old self - they are smart and simple. I think PF might appreciate them. For the full article, go here: Heres a summary:1. Create a framework of separate bank accounts: Checking, Retirement, Long term savings wedding, house, Short Term Savings vacation, Guilt Free Spending clothes, dining out, Emergency, Credit Card. 2. Set up automatic monthly deposits into each account. 3. Always, always, always avoid debt whenever possible. 4. Start investing in index funds as soon as possible. Not mutual funds. Not GIC. 5. Dont save mercilessly on the small things, only to spend carelessly on the big ones. 6. When you feel the need to buy something, put it out of your mind and wait 3 days. 7. Everything has 3 costs: the cost to acquire it, the cost of owning it, the opportunity cost of not using the money for something else. 8. Buy fewer things, and buy quality ones. 9. Money increases day-to-day happiness up to 75Kyear, above that - nope. Optimize for fulfilling work, not the highest paying. 10. Start a business. Youll value money more after learning how challenging it can be to earn it outside of employment. What do you think?  <response>: Nothing jumps out as bad advice, so yea. If you lived by that youd probably be more financially focused and reach the finish line retirement before those who dont.
