“Always leave room for the unexpected. A buffer of time, a little extra money, a reserve of goodwill.
You won’t be maximizing every opportunity or squeezing out every last dollar, but what you lose in reward, you gain in safety.
Survival is the highest return of all.” – James Clear
You can read this from a investment perspective, i.e. the importance of not blowing up your account. It’s also applicable for any activity you do on a repeated basis. Trying to maximize everything transaction or encounter is exhausting. It’s best to reserve your energy for the things that really matter.
