You will find the enthusiasm you are looking for. Follow your new priorities. Tiredness will be felt, you should run away, change your environment, get out of your routine.
You are right to feel confident, you are becoming healthier without making any conscious effort.
You will have the chance to give your best, perhaps because of your stubborn attitude. Keep your eyes peeled for some good deals.
Don't go out of your way to try to keep up with some of your peers. They work hard, but that doesn't mean they're effective.
You are entering a new phase emotionally. It's time to change course and lighten up, paying more attention to touch rather than your inner feelings.
