“If you want to have good ideas, you must have many ideas. Most of them will be wrong, and what you have to learn is which ones to throw away.” – Linus Pauling
To learn how to know which ideas to throw away you must take action. Without wondering what will happen if you perform a certain action, performing that action, observing the process and analyzing the results we’re just spectators.
Life is iterative. Meaning: it builds on itself, over time.
What you build on is up to you. Life, in a day-to-day sense, is not huge, grand high-stakes efforts. It’s more a choice between a series of procrastinations and just-getting-by or consistent daily and weekly action/learning experiments. Whichever you choose the effects accumulate.
Choose to act, and learn, and adapt.
