When you think you are too old to do something new remember you will never be younger than you are right now. - James Clear

Habits are the compound interest of self-improvement. The same way that money multiplies through compound interest, the effects of your habits multiply as you repeat them. They seem to make little difference on any given day and yet the impact they deliver over the months and years can be enormous. It is only when looking back two, five, or perhaps ten years later that the value of good habits and the cost of bad ones becomes strikingly apparent.

It's hard to grow beyond something if you won't let go of it.

The surest way to prevent yourself from learning a topic is to believe you already know it.
