The Pragmatic Programmer: your journey to mastery, 20th Anniversary Edition, 2nd Edition

Managing a knowledge portfolio is very similar to managing a financial portfolio: Serious investors invest regularly—as a habit. Diversification is the key to

long-term success. Smart investors balance their portfolios between conservative and high-risk, high-reward investments. Investors try to buy low and sell high for maximum return. Portfolios should be reviewed and rebalanced periodically.

Engineers prefer simple, singular solutions to problems.
