Enthusiasm is running high today in your collaborations. But you may be glossing over crucial details in the rush of melding minds with your co-conspirators. Big-picture scheming is great, but it can lead to making rash commitments. Right now, be especially careful when promising resources to others. Do you really want to go into business with that friend, lend your cousin that sweatshirt you love, or volunteer your Saturday to that neighbor’s cause? Check in with yourself before giving anyone your all. Your future self sends gratitude.
