Human: What is the best way to choose and purchase stocks for a long term investment? Assistant: 
The best way to choose and purchase stocks for a long term investment is to do your research, assess your financial goals, identify the types of investments that meet your needs, and compare the fees and services of different brokers. Additionally, consider diversifying your investments across various industries and countries if possible. Consult a financial advisor for advice if needed. Finally, once you decide which stocks to buy, set up a plan for reinvesting dividends and calculating the cost basis for any future taxes.
