Concentrate on goals and objectives. Block out distractions and avoid frivolous people. You have a wonderful opportunity to realise a cherished dream. Whether it's reaching your personal best with a physical challenge or finishing a creative project is immaterial. The important thing is to make some personal sacrifices for the sake of something bigger. Your loved ones will complain that you're unavailable. Don't bother defending your actions. All will be clear when you take your victory lap. Until then, keep your eyes on the prize.
