You are determined to win today. You want to conquer. Go for it.
Learning and analysing is your best defence against uncertainty at this time. You'll be confronted with situations and ideas that challenge you to think and act outside of your comfort zone. This is not something to be afraid of. See it for what it truly is; a chance for you to grow in unexpected and exciting ways.
If you make promises that you can't keep, people will begin to question your trustworthiness.
