Tired means you need rest. Lazy means you need a reason. Know which one you’re actually dealing with.

These two feel identical from the inside and need opposite treatment. Real tiredness means the tank is empty and pushing harder makes the next three days worse. The other thing is not a character flaw, it is usually a missing why: the task is vague, or it belongs to someone else’s plan. Rest will not fix that one, and a clear reason will.

When you cannot start, ask whether you could do something you love right now. If the answer is yes, you are looking for a reason, so go find one. If even that sounds like too much, you are tired, and stopping for tonight is the honest move.
