If there is something that you heard about, but don’t know what it is, look it up.
If there is a vegetable that you’ve seen but never tried, buy it and look up a recipe on how to cook it.
If a friend asks you to go to some new place/event and you’ve never experienced anything like it before, go for it.
Do not be afraid of trying new things. Most of the time, the economic cost is minimal. But to live a life to the fullest by experiencing as much of what it has to offer as possible? That’s invaluable.
