I always spend money on books and courses that help me make a big difference with a small change. Yes, you have those freeloaders out there who won’t spend anything on anything thinking they are saving a buck; but people like that rarely get ahead in life.
If you stay stagnant, if you say “I could find it somewhere else” would you actually do it?
Think about the value in a course from someone who spent years of their life understanding the material. Also, buying forces you to commit, and committing to something is how you get results.
