If you feel too energetic, you’ll become restless and crush everything in your way. Remember you need to achieve your goals, not crush them. If you’re restless throughout the journey, you’ll never enjoy the journey.
If you feel low on energy, you’ll become lethargic. Forget about reaching the goal, you’ll be too tired to even think about it. If you don’t achieve anything, you’ll feel that you can’t do anything, which is a defeating mindset.
To overcome the lows and highs, you need to counterbalance them. If you’re flying to high, slow down. If you’re flying too low, pick up the pace, just enough to avoid a crash.
