Burning the candle at both ends is rarely sustainable and I'm wondering if this is the cause for the recent lack of focus I've been experiencing. Regardless of where I am or what I'm doing, the mind will wander mid-process which can result in emails being left unattended, code being half-written, and conversations being tuned out of. As one can imagine, this isn't cool. Is the lack of focus a different kind of burn-out, or is it just a result of getting older?
