Now that your task is finished, you can enjoy the fruits of your labour.
You're being faced with a choice. Either you allow nervousness and fear to hold you back and prevent you from moving forward, or you step step forward bravely into the unknown future. Take a step out of your comfort zone and investigate further. By doing something out of the ordinary every now and then, you'll build your courage and your capacity to face new challenges.
What works best for someone else may not work well for you. Listen to their advice, but think critically about whether or not it is right for you at this time.
