From my vantage point of almost 64 years of life, let me give you some suggestions for finding your role in God's kingdom:
1. Try new things!
Don't limit yourself, especially during the first 40-50 years of your life. Doing a variety of things, even things out of your comfort zone, teaches you important lessons. (How, Not What).
2. Humbly learn from others.
I once edited submissions to a devotional blog, and I learned that many mediocre writers refuse suggestions or edits while most good writers want them (Proverbs 4:13, Proverbs 23:22, 1 Peter 5:5).
3. Never stop learning.
There's always something new to learn. Regularly seek improvement (Colossians 3:23, Waste or Invest)
4. Set your mind on God's plan.
Despite the popular saying that we can do whatever we set our minds to do, we can't and we shouldn't. We need to seek God's will, not ours (1 Peter 4:10-11, You Can't).
