1 Timothy 4:12, Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
If you have the privilege of working a “secular” job, make it part of your ministry. God has placed you there to shine His Grace and Mercy for someone who needs it. Shine the joyful spirit of Jesus Christ. Make opportunities to share the Gospel. Be thou an example!
